Data Loss Prevention overview
Stop data theft before it happens – with real-time alerts, early leaver detection and enterprise-grade forensics.
Most SMEs only discover insider data theft months after it’s happened. By then, the damage is done – clients poached, data lost, evidence gone.
This service changes that.
Built on the Microsoft Purview Suite for Microsoft 365 Business Premium, Atlas Cloud brings insider risk protection normally reserved for enterprise security teams directly into the hands of SMEs – wrapped in a fully managed service, tailored to your industry and risk appetite.
CHECKLIST
- Identify leavers before they hand in their notice.
- See data leaving your organisation in real time.
- Act while it’s still recoverable.
- And hold the evidence if you need to pursue a claim.
Why insider risk matters now
Data loss doesn’t always look like a cyberattack.
More often, it’s a trusted user – or someone accessing their account – quietly preparing an exit.
Common signals include:
- Sudden downloads of client or candidate data
- USB copying
- Forwarding spreadsheets to personal email
- Deleting SharePoint or OneDrive files
- Removing sensitivity labels
- Logging in from unusual locations or anonymous IP addresses
- Activity spikes moments before or after giving notice
These actions rarely happen in isolation. Together, they paint a clear picture that someone is preparing to leave – weeks before they tell you.
This service lets you see that picture in real time.
The power of real-time visibility
Detect and intervene – instantly
When suspicious activity happens, you receive real-time alerts with the forensic detail needed to act immediately.
YOUR INSIGHT:
- Who accessed what
- From which device/IP
- What they copied, shared or deleted
- Which files were involved
- The exact sequence and timestamp of actions
letting you:
- Lock the account and stop the exfiltration
- Recover stolen data
- Take internal action
- Protect clients and commercially sensitive information
- preserve evidence that stands up in legal or HR proceedings
Enterprise-grade technology – without the enterprise price tag
Until recently, this level of insider risk protection required:
- Expensive, enterprise-grade technology
- Internal security teams
- Dedicated investigators
- Specialist forensic tooling
That put it out of reach for smaller organisations. But not anymore.
Microsoft’s Purview Suite brings enterprise-class telemetry, behavioural indicators and forensic evidence to organisations using Business Premium licences. Atlas Cloud turns that capability into a simple, cost-effective, fully managed service for SMEs.
You thought this wasn’t possible for your firm. It is.
Industry-specific protection
Recruitment agencies
Recruitment is high risk – consultants leave, set up on their own and take pipelines with them.
Protect against:
- CV databases being copied to USB
- Client/candidate sheets forwarded externally
- Large file downloads just before notice is given
- Unusual IP access from outside normal working locations
- Sensitive files deleted after a resignation
law frims & chambers
With Insider Risk Protection you can detect:
- Members exporting case bundles externally
- Legal documents shared without sensitivity labels
- SharePoint deletions during offboarding
- Self-employed barristers using unapproved tools
- Unusual login activity on chambers-owned devices
Compliance expectations are rising. This closes one of the biggest blind spots in legal IT.
Finance & regulated industries
With Insider Risk Protection you can detect:
- Client lists forwarded to personal accounts
- Financial data downloaded to personal devices
- Remote access attempts from unfamiliar locations
- Deletion or modification of sensitive documents
High-trust environments demand high accountability.
What Atlas Cloud manages for you
Insider risk protection only works if it’s configured, monitored and interpreted properly – which is why we handle everything.
Atlas Cloud builds and maintains industry-specific policy templates for your organisation, covering leaver detection, sensitive data monitoring, unusual access patterns, USB usage, cloud-to-cloud transfers and more.
We continuously ingest telemetry from Microsoft Purview and turn this raw signal into meaningful, real-time alerts that you can act on.
For SMEs with 20+ users
This service is designed for SMEs that hold commercially sensitive information but don’t have the resources for a dedicated security team.
Whether you’re a recruitment agency protecting candidate databases, a solicitor firm safeguarding case files, a barristers’ chamber managing independent members, or a finance team controlling regulated data, the underlying need is the same: real-time visibility when someone starts preparing to leave – not weeks after the damage is done.
