Secure data.
Enable the mission.

Prosper Cyber is a data security advisory practice for regulated enterprises and public-sector agencies. We design and deploy Microsoft Purview, DLP, and DSPM programs that cut risk without getting in the way of the cloud, SaaS, and AI work you're already trying to ship.

How we operate

Built for regulated environments where downtime is not an option.

Transportation, healthcare, financial services, government. Each one carries its own data obligations: CJIS, HIPAA, SOC 2. Our practice was built around those from day one, not retrofitted later.

Enablement-first security

Security holds up best when it's the default path through a workflow, not a gate people route around. Clinicians, engineers, agents all keep doing their jobs. The risk stays contained.

Hybrid pre-sales & delivery

Architect Monday, demo for executives Tuesday, ship a tuned DLP policy Wednesday. One person covering the full arc means less context is lost between meetings, and the thing actually ships.

Mission-aligned outcomes

Every control we recommend ties back to something measurable: risk reduced, cost avoided, or time given back to the people doing the work. Controls that exist only to satisfy an auditor are a waste of budget.

Microsoft Purview SME

The Purview practice, end to end.

Most teams buy Purview and end up using maybe a quarter of what they paid for. We design the taxonomy, roll out the policies, tune the signals, and leave you with something your team can actually run. Dashboards included, and the kind your executives won't wince at in a board review.

  • End-to-end Purview architecture (E3 & E5)
  • Phased rollout with measurable risk reduction per phase
  • Tight coupling with Defender, Entra, and Sentinel
  • Knowledge transfer that leaves teams self-sufficient

Information Protection

  • · Sensitivity label taxonomy & auto-labeling
  • · Exact Data Match (EDM) classifiers
  • · Trainable classifiers & keyword dictionaries
  • · Service-side & client-side labeling strategy

Data Loss Prevention

  • · Endpoint, Teams, Exchange, SharePoint, OneDrive
  • · Chrome / Edge browser extension DLP
  • · Policy tuning & false-positive reduction
  • · Adaptive Protection signal integration

Insider Risk Management

  • · Risk indicators & custom policies
  • · HR connector & Adaptive Protection
  • · Forensic evidence & analyst triage
  • · Workflow escalation into SOC

Data Security Posture (DSPM)

  • · Sensitive data discovery across M365 & cloud
  • · Overshared data & access remediation
  • · AI Hub — governance for Copilot & GenAI
  • · Posture scoring & executive reporting

eDiscovery & Compliance Manager

  • · HIPAA, NIST 800-53, CJIS assessments
  • · eDiscovery (Premium) case management
  • · Audit log analytics & retention policies
  • · Regulatory alignment roadmaps

Integration Fabric

  • · Entra ID · Conditional Access · MFA step-up
  • · Defender for Cloud Apps (MDCA) stitching
  • · Netskope, Symantec DLP co-existence
  • · SIEM / SOAR forwarding (Sentinel)
Service portfolio

Six practices. One outcome: secure enablement.

01

Data Protection & DLP Programs

Enterprise DLP design and implementation, insider risk mitigation, and endpoint + SaaS coverage. Rollouts phased by business unit to contain change risk.

02

DSPM & Data Visibility

Find where the sensitive data actually lives, including the shadow stuff nobody documented. Fix by risk, not by whatever the scanner happened to flag first.

M365 + cloud scanningOversharing remediationCopilot readinessSprawl reduction
03

Compliance & Governance

HIPAA-aligned controls, CJIS readiness for public-sector agencies, and audit programs that survive external review.

Cloud & SaaS Security Architecture

Microsoft-centric security design, CASB/SSE implementation, and cloud data protection patterns that scale across workloads.

Third-Party & Vendor Risk

Session-isolated vendor access, sensitivity-based segmentation, and a complete audit trail for every session. Vendors keep working the way they already work; your blast radius stays small.

Case studies

Delivered under audit pressure.

Three engagements across healthcare, SaaS, and financial services. Each one had auditors watching and a deadline the client couldn't miss. Here's what shipped.

Case 01HIPAA · Clinical workflow

Securing PHI without slowing clinicians

Healthcare System
92%
PHI exfiltration risk reduced
100%
Audit log coverage
40%
Faster access vs VDI
0
Workflow disruptions
Challenge
  • Prevent PHI leakage from EHR systems
  • Maintain sub-second clinical workflows
  • Reduce reliance on expensive VDI infrastructure
Solution
  • Browser-based secure access with FHIR-API role scoping
  • Step-up MFA on high-risk clinical actions
  • Clipboard, download, screenshot, and upload controls
  • Full session auditing tied to audit logs
Impact

HIPAA audit closed with zero critical findings. The client sidestepped a VDI rebuild that would have run into seven figures. Clinicians got remote access that doesn't feel like remote access.

Case 02Cloud migration · Purview-led

Secure data-center-to-cloud migration

B2B SaaS Platform
0
Critical exposure incidents
75%
Redundant data eliminated
60%
Over-permissioned access cut
100%
Classified data coverage
Challenge
  • Unknown data exposure across legacy estate
  • No unified governance model for cloud
  • Risk of misconfigured cloud storage during cutover
Solution
  • Enterprise data mapping + classification with Microsoft Purview
  • Least-privilege access and sensitivity-based segmentation
  • Continuous DSPM + SaaS DLP enforcement post-cutover
  • Encryption in transit and at rest across all tiers
Impact

The migration shipped 30% ahead of schedule. No mid-cutover surprises, no cleanup project afterward. The cloud foundation was locked down before anything else got built on top of it.

Case 03GLBA · SOC 2 · Vendor risk

Third-party data risk, brought under control

Financial Institution
90%
Unauthorized vendor access reduced
100%
Vendor activity visibility
80%
Risky data sharing reduced
Full
Audit compliance alignment
Challenge
  • Limited visibility into vendor data access
  • Inconsistent enforcement across business units
  • Regulatory pressure from GLBA and SOC 2 audits
Solution
  • Session-isolated vendor environments with clipboard + download blocks
  • Role-based, sensitivity-segmented vendor access
  • Full vendor session logging with anomaly detection
  • SaaS + API-level DLP across data in use, motion, and rest
Impact

Auditors walked away satisfied on both GLBA and SOC 2. Vendor teams kept working the way they already worked. Third-party exposure dropped to something the risk committee could actually sign off on.

Public sector & enterprise consulting

Tailored for agencies and global integrators.

Two common setups: embedded as a subject-matter expert inside a prime integrator's delivery team, or contracted directly with an agency security office. Controls map to CJIS, NIST 800-53, and the state frameworks that show up in your actual audit. They also map to how DOT, health, and transportation agencies work day to day, not just how the policy doc describes them.

Global systems integrators
Embedded Purview / DLP / DSPM capacity for fixed-fee engagements. We slot into your delivery team as SME depth, not as a competing brand in front of your client.
State & transportation agencies
Data protection programs aligned to TxDIR, CJIS, and PII/CUI obligations, with rollout cadences that respect procurement and change windows.
Healthcare & public-benefit orgs
HIPAA-hardened workflows clinicians will actually use. Browser-based secure access instead of a VDI buildout nobody wants to own.

Microsoft Purview — Information Protection & DLP
What this profile brings to a delivery team

Enterprise security architecture · data protection · cloud transformation · third-party risk · AI governance. One person covering pre-sales, architecture, and delivery. Fewer handoffs, less context lost between meetings, and a shorter path from kickoff to controls running in production.

Engagement model

Four phases. Measurable exit criteria at each.

Typical engagement: 12–24 weeks. Longer for agency-scale rollouts, shorter for targeted SME augmentation inside an integrator's delivery team.
01

Discover

Two to three weeks to get a clear picture: where your data sits today, where the risk is concentrated, what your auditors actually care about, and who needs a seat at the table.

02
