Semperis
Identity security vendor that recovers Active Directory after cyberattacks.
On the record
Checkpoint: Cayosoft FY26 renewal win-rate data and MightyID integration results become clear
The call
Semperis sits inside Microsoft's own security stack as the recovery layer Microsoft won't build itself, while Cayosoft and AI copilots press at its edges.
Semperis builds emergency backup and recovery tools for Active Directory, the system most companies use to manage employee access and data. It is difficult for rivals to copy because Microsoft itself chose to use Semperis technology instead of building the feature alone, and because no company wants to buy 'recovery tools' from the company whose product they are recovering from. The biggest risk is if Microsoft decides to add these recovery features directly into its own security products, which would expose Semperis to losing customers who prefer to buy everything from one vendor.
Why
01
AI pressure: Generic SOC AI copilots (e.g., Microsoft Security Copilot). AI copilots can automate anomaly detection, squeezing that layer's value, but Semperis keeps the recovery workflows and forensic data proprietary. Could AI do the core job? Unlikely.
02
Bigger players: Microsoft (potential native identity-recovery build). Microsoft could build native AD recovery into Defender or Entra, but pitching 'recover from our own breach' is a hard sell for them. Could a giant copy it? Probably.
03
What protects it. Patented independent recovery tech, NSA/CISA endorsement, and deep Microsoft co-sell distribution keep customers locked into its workflows.
What would change this call
Semperis or peers disclose renewal win/loss rates against Cayosoft in FY26. Would show whether Cayosoft is actually converting marketing claims into won accounts.
Microsoft ships a native AD identity-recovery product beyond current Sentinel/Copilot integration. Would show Microsoft abandoning its co-sell stance and competing directly on recovery.
Semperis 2027 ARR growth rate compared to prior years after MightyID integration. Would show whether the first acquisition helped or stalled growth momentum.

Key numbers
- $100M+ ARR, 3000%+ five-year growth
- >$1B valuation after $125M raise
- MightyID acquired, adds Okta/Ping coverage
Named risks
- Cayosoft aggressively marketing documented customer defections from Semperis.
- MightyID acquisition integration execution risk as Semperis's first M and A deal expanding beyond Microsoft stack.
- No new primary funding round since June 2024 despite passing $100M ARR, leaving valuation and growth updates unverified.
- Newly disclosed critical AD vulnerabilities (KerberLoss, ResetNightmare) could be exploited before customers patch.
- Generic AI SOC copilots could commoditize anomaly detection layer if not tightly integrated with proprietary telemetry.

Questions people ask
- Is Semperis profitable in 2026?
- Semperis has not disclosed profitability. It reported surpassing $100M in ARR on January 30, 2025, with 3,000%+ growth over five years, but no public net income or profit figures have been released as of mid 2026.
- Who owns Semperis?
- Semperis is privately held and venture backed, not publicly traded. Investors include KKR, Insight Partners, Ten Eleven Ventures, Paladin Capital, and Atrium Health Strategic Fund, with a June 2024 financing from J.P. Morgan and Hercules Capital valuing it above $1 billion.
- What is Semperis's biggest competitor?
- Cayosoft is Semperis's most aggressive direct rival, publicly marketing customer defections including a documented case (DOIT) of a customer switching away from Semperis, as noted in a February 11, 2026 Cayosoft case study.
- Could AI replace Semperis?
- Unlikely soon. Semperis's moat rests on patented AD-decoupled recovery tech, NSA/CISA-endorsed tools, and proprietary incident-response data, areas AI copilots feed into rather than replace, as shown by its June 23, 2026 Microsoft Sentinel and Security Copilot integration.
- Is Semperis a safe company to join in 2026?
- Signals are positive: headcount grew to about 652 employees by December 2025 (+26.6% YoY) per Revelio Labs, with 106 new job postings in 2025 (+46.5% YoY), plus continued office expansion in Texas and Canada announced February 2025.
- How much funding has Semperis raised?
- Semperis has raised roughly $379M-$382M total across rounds as of April 2026, including a $200M+ Series C led by KKR (closed around January 2023) and a $125M growth financing from J.P. Morgan and Hercules Capital in June 2024.
