Microsoft Purview practice

Microsoft Purview implementation for Australian organisations

We set up Microsoft Purview inside your Microsoft 365 and stay to run it. Your sensitive files get labels and protections that follow them, so Copilot and AI agents only work with what each person is meant to see. When an auditor or a regulator asks what you kept and why, you can show them.

Microsoft Purview at work: files carry sensitivity labels inside a protected boundary. Copilot reads an approved policy, an AI agent asking for payroll data is blocked, and a bulk download by someone leaving raises an insider-risk alert.

What we hear

Problems Purview solves, in your words

  • "We're switching on Copilot next month, and I don't know what it will dig up."
  • "Someone built an agent in Copilot Studio and connected it to the HR site."
  • "A manager left for a competitor on Friday. I can't tell what went with them."
  • "Our client list went out as an email attachment, to the wrong person."
  • "The auditor asked how long we keep rates records and how we dispose of them. We couldn't show it."
  • "We're retiring the old records system, and nobody has said what replaces it."
  • "If we had a breach tomorrow, I couldn't tell the OAIC which records were involved."

Each of these has a fix inside Microsoft 365. If you're on Microsoft 365 E3 or Business Premium, you already own part of Purview, so we start by checking which parts are switched on and which you'd still need.

In plain words

What Microsoft Purview is

Microsoft Purview is the part of Microsoft 365 that protects your organisation's information and keeps track of it. It works across Outlook, Teams, SharePoint, OneDrive and your Windows and Mac computers, and it now covers Copilot and AI agents as well. Most of it runs in the background. Staff see a tag at the top of a document, or a warning before they send something they shouldn't. Behind that sit the rules about who can open what and how long each record is kept, plus a log of who did what.

  • Outlook
  • Teams
  • SharePoint
  • OneDrive
  • Windows and Mac
  • Copilot
  • AI agents

Capabilities

What Purview does, job by job

01

Know what you hold and where it sits

  • Sensitive information types
  • Trainable classifiers
  • Content explorer
  • DSPM

Purview scans email, Teams, SharePoint and OneDrive for sensitive information. It uses built-in detectors, called sensitive information types, that recognise things like Australian tax file numbers, and classifiers you can train on your own documents, such as contracts or case notes. Content explorer shows where those items are.

Data Security Posture Management (DSPM) is a dashboard that pulls Purview's findings into one view. Its oversharing checks find content that is open to far more people than need it. Microsoft's own Copilot guidance puts fixing that first.

02

Protect it wherever it goes

  • Sensitivity labels
  • Data loss prevention
  • Endpoint DLP
  • Information barriers

Sensitivity labels are tags on files and emails that decide who can open them and what they can do with them. A label can add a "Confidential" footer, stop forwarding or encrypt the file. When a label encrypts a file, the protection stays with it, so a copy that ends up outside your organisation still only opens for the people the label allows. Staff can apply labels themselves, or Purview can apply them automatically when it finds sensitive content.

Data loss prevention (DLP) rules spot sensitive information as people work and step in before it leaves. That might be a tip in Outlook, a warning that needs a reason to override, or a block. DLP covers email, Teams, SharePoint and OneDrive. On managed computers it can also stop files being copied to a USB drive, or sensitive text being pasted into a public AI tool in the browser.

Where two teams must not share information, such as two sides of a deal, information barriers stop them finding or messaging each other.

03

Keep it, or delete it, on schedule

  • Retention policies
  • Retention labels
  • Records management
  • Disposition review

Retention policies keep or delete content after a set period. Retention labels go further. They say how long a document must be kept and what happens at the end, and they can start the clock from an event, such as a contract ending or a staff member leaving.

Records management can lock an item as a record so nobody edits or deletes it. When the retention period ends, a named person approves the destruction in a disposition review, and Purview keeps proof of what was destroyed and when. If a dispute or an information request arrives, a hold stops the relevant content being deleted until it's resolved.

04

Watch for risky behaviour

  • Insider Risk Management
  • Communication Compliance

Insider Risk Management looks for patterns that suggest data theft or a leak, for example a burst of downloads or uploads to personal cloud storage in the weeks before someone's last day. It can read resignation dates from your HR system so it knows when to look. Names are hidden by default, so analysts review the pattern before they see the person.

Communication Compliance does a similar job for messages and AI prompts. It flags things like sensitive information pasted into a chat, or harassment.

05

Prove what happened

  • Audit
  • eDiscovery
  • Compliance Manager

Purview's audit log records what staff and admins did across Microsoft 365, including Copilot prompts and the files Copilot used to answer them. The standard plan keeps 180 days. Audit (Premium) keeps a year for the main services by default, and up to ten years with an add-on.

eDiscovery lets you search, hold and export content for legal matters and information requests. Compliance Manager scores you against assessment templates, including the Essential Eight, and lists the actions that would raise your score. When a regulator or a court asks what happened, these are the records you answer from.

06

Make Copilot and AI agents safe to switch on

  • DLP for Copilot
  • DSPM for AI
  • SharePoint Advanced Management
  • Agent inventory

Microsoft 365 Copilot answers using whatever the signed-in person is allowed to open. That's the right rule, but it means every folder shared too widely over the years becomes something Copilot can find and summarise on request.

Purview closes that gap in several ways. If a label encrypts a file, Copilot can only use it when that person's rights include copying content out of it (Microsoft calls this EXTRACT) as well as viewing it. DLP rules for Copilot can keep files with chosen labels out of its answers. Copilot may still list the file, but it won't read or summarise it. Other rules stop Copilot searching the web when a prompt contains sensitive details, and Microsoft is rolling out rules that block those prompts altogether. When Copilot in Word, PowerPoint or Outlook drafts from a labelled document, the new document takes on the same label.

AI agents are assistants that act on someone's behalf, such as one built in Copilot Studio to answer HR questions. Purview treats Microsoft's agents much like staff. They can be put under DLP, insider risk and retention rules, and DSPM keeps an inventory of the agents in use. It flags risky activity, such as an agent opening sensitive files or sharing them outside the organisation. Prompts and responses are logged, and you can keep or delete them on a schedule, like email.

For fixes at site level, SharePoint Advanced Management comes with Copilot licences. It reviews who can reach each site and can hide sensitive sites from Copilot while you clean them up.

AI

AI makes old sharing mistakes visible

Microsoft's own guidance says generative AI raises the risk of oversharing and leaks, because it surfaces content so quickly. A file that sat unnoticed in an open folder for six years can now turn up in a summary for anyone who asks the right question.

Breaches

Breaches are getting bigger

Australian organisations reported 667 data breaches to the OAIC from January to June 2026, about the same as the half before. The count barely moved, but breaches affecting more than a million people rose from 4 to 11. Across 2025 the OAIC received 1,205 notifications, the most since the scheme began in 2018, and malicious or criminal attacks remain the main cause.

The Privacy Commissioner's advice was that organisations "can't lose personal information they don't hold". Retention rules that delete what you no longer need make the next breach smaller.

Cybercrime

Cybercrime costs mid-sized organisations more

ASD's Annual Cyber Threat Report 2025-26 counted more than 82,000 cybercrime reports, about one every six minutes. The average reported cost for a medium business rose 45% to $141,300. For a small business it was $55,400.

Purview doesn't stop attackers getting in. That's the job of the Essential Eight and your security tools. Encrypted labels limit what an attacker can read if they do get in, and the audit log tells you quickly what they touched.

Privacy law

Privacy law expects technical controls

Since December 2024 the Privacy Act has said that reasonable steps to protect personal information include technical and organisational measures. From December 2026, privacy policies must explain when personal information is used in automated decisions that significantly affect people, including decisions made largely by computer programs such as AI tools. A statutory tort for serious invasions of privacy also lets individuals take action directly.

Purview is the technical side of this inside Microsoft 365: labels, DLP, retention and the audit trail. Your lawyers decide what the law asks of you, and we build the controls that meet it.

Records law

Records law for councils and public bodies

Councils keep records under state law: the State Records Act 1998 in New South Wales, the Public Records Act 1973 in Victoria and the new Public Records Act 2023 in Queensland. Each expects records to be kept for set periods and destroyed only under an authorised disposal schedule.

Retention labels and disposition review let you apply your disposal schedule inside Microsoft 365 and keep proof of each destruction. Most of the effort goes into mapping the schedule's classes to labels, with your records team.

Finance

Regulated finance

Under APRA's CPS 234, regulated entities must classify information assets by criticality and sensitivity, and tell APRA within 72 hours of a material information security incident. Sensitivity labels are a direct way to classify by sensitivity in Microsoft 365, and the audit log is where the incident timeline comes from. CPS 230, in force since July 2025, adds operational risk duties. Purview supports the evidence for those, though it isn't a CPS 230 tool.

Your IP

Staff departures and your intellectual property

Client lists, pricing models, tender responses and designs are hard to replace and easy to copy. When someone leaves for a competitor, a scoped insider risk policy flags unusual downloads and sharing in their last weeks, and DLP closes the obvious routes out, like forwarding files to a personal email address. You see it while it's happening, and you have a record if you need one later.

Deadlines

When something goes wrong, the clock starts

Several obligations run on short deadlines. APRA expects to hear about material incidents within 72 hours. Under the Cyber Security Act 2024, many businesses must report a ransomware payment within 72 hours. Any breach assessment has to establish what information was involved. Those answers come faster from an audit log and an eDiscovery search than from people's memories.

Essential Eight

Where the Essential Eight fits

The Essential Eight is ASD's baseline of eight protections for devices and accounts, such as multi-factor authentication, patching, restricted admin rights and backups. None of them is a Purview control. The Essential Eight makes it harder for attackers to get into your systems, and Purview protects the information inside them. If multi-factor authentication is patchy or admin accounts are open to everyone, a label won't save you, so we check both.

They overlap in two places. Compliance Manager can track your Essential Eight maturity over time. And retention is a different thing from backups: retention keeps records for legal reasons, while backups get systems running again after a loss.

How we work

How we implement Purview

Every project is shaped around your organisation and your Microsoft 365 setup. Like all our work, it moves from map to route to climb, in five phases. Timings are typical ranges, and larger organisations run them in waves.

  1. 1Map

    Discovery and data map

    ~2 to 3 weeks

    We check your licences and current settings, scan for sensitive information, run an oversharing assessment and talk to the people who own the risk: records, privacy, IT, HR and the business. You get a data map that shows where sensitive information sits and who can reach it, plus a one-page plan with the order of work.

  2. 2Route

    Design

    ~2 to 4 weeks

    We design a small label scheme that staff can understand, aligned with the classification your jurisdiction or sector uses. We write the DLP rules, map your retention or disposal schedule to labels, agree the insider risk scope with HR and legal, and set the Copilot and agent controls. Every rule gets a reason in plain English, so staff know why they're seeing a warning.

  3. 3Climb

    Pilot in simulation

    ~4 to 8 weeks

    Policies run in simulation first. They log what they would have blocked without stopping anyone, while a pilot group starts using labels. We go through the results with you and fit each rule to how your people actually work.

  4. 4Climb

    Enforce in waves

    Once the rules flag only what they should, we switch on enforcement for the pilot group, then widen it wave by wave, with training and a short guide for each group. Insider risk policies go live only after staff have been told they exist.

  5. 5Climb

    Run and improve

    ongoing

    Your business keeps changing, and Purview keeps up with it. New sites appear, people build agents, staff change roles and Microsoft keeps adding to the product. We review alerts with your team, adjust the rules as your work changes, extend labels and policies to new places, and re-check your four Data Trust pillars each quarter. The people who design your labels are the people who switch them on and answer the alerts afterwards.

Deliverables

What you get

What's in scope depends on your licences and priorities. A full implementation includes:

  • A data map of where sensitive information sits and who can reach it, including your most overshared sites.
  • A one-page plan with the order of work.
  • A label scheme, with the rule behind each label and staff guidance in plain English.
  • DLP policies for email, Teams, SharePoint, OneDrive, devices and Copilot, tested in simulation before they block anything.
  • Retention and records settings mapped to your retention or disposal schedule, with a tested hold and search.
  • Insider risk policies scoped with HR and legal, and a playbook for each type of alert.
  • Copilot and agent controls: oversharing fixes, Copilot DLP rules and an inventory of the agents in use.
  • Audit settings that let you reconstruct an incident.
  • Training for staff and admins, and a run book your team can follow.
  • Quarterly reviews against the four Data Trust pillars.

Licensing

Which licences you need

Purview comes with your Microsoft 365 plan, in tiers.

Included with Microsoft 365 E3 or Business PremiumNeeds Microsoft 365 E5 or a Purview add-on
Sensitivity labels that staff applyAutomatic labelling
DLP for email, SharePoint and OneDriveDLP for Teams and devices

Insider Risk Management and Communication Compliance

A few features are charged by usage, mostly for data and AI apps outside Microsoft 365, and controls for agents built outside Microsoft 365 need newer Microsoft licences. If you have Copilot licences, SharePoint Advanced Management is included.

Microsoft renames and rebundles these licences often, so treat this table as a guide. We check your tenant before we recommend anything, and if a capability needs a licence you don't have, we tell you before you commit. Neural Peak is an independent consultancy and isn't affiliated with or endorsed by Microsoft.

Sectors

Who we do this for

Local government and public sector

Councils and agencies with records obligations, information requests and a records system to retire or connect. We design labels that fit your state's classification, map your disposal authority to retention labels and get Copilot ready without exposing sensitive community information.

Use cases for local government →

Finance and wealth management

Funds, advisers and wealth managers, where client financial information is the most sensitive thing you hold and advisers move between firms. We set up insider risk policies for adviser departures, and labels and DLP for client documents. For APRA-regulated entities, the label scheme can support CPS 234 classification by sensitivity.

Use cases for finance →

Education and migration

Agencies, providers and migration firms that hold passports, visa histories and student records, often spread across email and shared drives. We find where that personal information sits, label it, and keep it only as long as you need it.

Use cases for education and migration →

Professional services

Law, accounting and advisory firms that manage client confidentiality and legal holds. We set up labels and DLP for client material, information barriers between teams where you need them, retention schedules and a tested hold and search.

Use cases for professional services →

Not-for-profits

Charities and community services that hold case notes and health details, often with volunteers on personal devices and a small IT team. We scale Purview to what you have, and the free Data Trust Review is a good place to start.

LiveWhole of council

Purview we run today

We currently run Microsoft Purview for one of Australia's largest local governments. It's live across the whole council and covers sensitivity labels, data loss prevention, records management and insider-risk controls, as legacy records systems are retired. We don't name the council, because the work belongs to them, and we don't publish figures for it.

Running it has shaped how we work. We pilot every policy before enforcing it, and we get records, privacy, IT and HR working from one plan, because labels, retention and insider risk rules all act on the same files. After go-live we stay on to run it and keep it in step with your business.

FAQ

Questions we hear

Do we already have Microsoft Purview?

Partly. Microsoft 365 E3 and Business Premium include sensitivity labels that staff apply, DLP for email, SharePoint and OneDrive, retention policies, a 180-day audit log and standard eDiscovery. Automatic labelling, DLP for Teams and devices, keeping labelled files out of Copilot, records management, insider risk and longer audit history need E5 or a Purview add-on. We check your tenant first and tell you what you can do with what you already pay for.

Is Microsoft Purview free?

There's no separate bill for the parts that come with your Microsoft 365 plan. The advanced parts need E5 or an add-on licence for each user who benefits. A few features, mostly for data and AI apps outside Microsoft 365, are charged by usage through an Azure subscription. Our implementation work is separate from Microsoft's licences.

Do we need Purview before we turn on Copilot?

You don't need all of it, but you need the basics first. Microsoft's own Copilot deployment guidance starts with fixing oversharing, then setting guardrails, then meeting regulatory requirements. In practice that means finding and fixing your most overshared sites, labelling your most sensitive content, checking that audit is on, and rolling Copilot out in groups.

Will Copilot show our staff files they shouldn't see?

It can. Copilot answers using whatever the signed-in person is allowed to open, so a folder shared with everyone years ago becomes something it can find and summarise on request. The fix is to find the oversharing, tighten access on the worst sites, label sensitive material and add DLP rules that keep labelled files out of Copilot's answers. We do this before a rollout, or alongside one.

Can Purview control AI agents, like ones built in Copilot Studio?

Yes, for Microsoft's agent platforms. Copilot Studio and Microsoft Foundry agents can be covered by sensitivity labels, DLP and insider risk policies, and agents managed through Agent 365 are added to policies the way you'd add a person. Purview's posture dashboard lists the agents in use and flags risky activity, such as an agent opening sensitive files or sharing them outside the organisation. Some agent controls need newer Microsoft licences, so we check that first.

Can Purview stop staff pasting sensitive information into ChatGPT?

On managed Windows computers, yes. Endpoint DLP can warn or block when someone pastes sensitive information, such as card numbers or tax file numbers, into a generative AI website. Some browser and network controls are charged by usage. It works best alongside a clear AI use policy, so staff know which tools they're allowed to use.

Will DLP get in the way of people doing their jobs?

Not when it's set up with care. We run every policy in simulation first and read what it would have blocked, so each rule fits how your people actually work before it blocks anything. We pilot with a small group, then widen, and every warning tells staff why it appeared.

How long does a Purview implementation take?

It depends on your size and scope. Discovery and a data map typically take ~2 to 3 weeks. Labels and DLP for a first group typically follow within ~4 to 10 weeks. Records management and insider risk add phases after that, so a rollout across a whole organisation runs over several months. You get a plan with dates after discovery.

Can Purview replace our records management system?

For many organisations it can manage records inside Microsoft 365. Retention labels apply your disposal schedule, items can be locked as records, and destruction goes through a review that keeps proof. Whether it replaces your current records system depends on your record types, your integrations and how much sits outside Microsoft 365. At the council we work with, Purview's records management runs as legacy records systems are retired. We plan that kind of move with your records team, against your disposal authority.

Isn't insider risk monitoring invasive for our staff?

It can be if it's done badly. We design it with your HR and legal teams and scope it to defined groups, such as departing staff. Staff are told the monitoring exists. Purview hides names by default, so analysts look at the pattern before they see the person.

Does Purview make us compliant with the Privacy Act or the Essential Eight?

No tool does that on its own. Purview gives you the controls and the evidence for the parts of privacy and records law that deal with protecting information and keeping or disposing of it. The Essential Eight is a separate set of eight protections for devices and accounts, such as multi-factor authentication and backups, and Purview isn't one of them. We map your obligations to controls and leave legal advice to your lawyers.

What happens after go-live?

We stay on and run it with you. We review alerts with your team, adjust the rules as your work changes, label new sites and agents as they appear, and keep up with Microsoft's changes. Each quarter we re-check the four Data Trust pillars, so you can see progress.
