Continuous adversarial validation
Attack-Proven Defence.
Keelr attacks, Panthero defends, the loop never stops - autonomous adversarial validation, EU-sovereign by design.
Through 14 July 2026: 25% off annual, 15% off monthly. Founding rate locks as long as you stay on the same tier.
Four pillars
Everything Keelr does rolls up into one of these.
Adversarial simulation
Continuous, authorised attack simulation across your attack surface. Exposure discovery across vulnerabilities, misconfigurations, logic flaws, exposed services, and policy gaps.
Authorisation posture
Scope-bound, time-boxed, signed, revocable, audit-logged. Pillar 1 cannot run without pillar 2. Attempted engagements outside scope fail closed, every time.
Finding intelligence
Dedup across scans, severity on a 0-100 five-bucket scale shared with Panthero, exploitability labelled validated or theoretical, full findings library and history.
Proves Panthero
The loop wiring: export findings, receive re-attack requests, validate fixes by re-running the exact exploit path. Activates when you run Keelr with Panthero as the Loop bundle.

Why only us
The structural wedge.
Defensive incumbents cannot run offence honestly.
They would need to acquire an offensive vendor, integrate two cultures, sell two tools. Even then, the result is two products bolted together - not a loop.
Offensive incumbents cannot own remediation.
The best autonomous-pentest platforms stop at the finding. Closing the loop would turn them into a managed service and kill their product economics.
Only a purpose-built loop can sell attack-proven defence.
Keelr and Panthero are siblings by design. One company, one stack, one pricing motion. Zero integration tax. Structurally impossible to fake.
Autonomy, without abandonment
Autonomous to staging. Human-approved for production.
The Agents run without supervision. They pick the engagement, write the probe, triage the finding, draft the remediation. Staging gets fixes applied and re-attacked automatically.
Production stays yours. Fixes land in your production on your word, through the gate we designed specifically so the loop closes without the liability the rest of the market never solved.
EU sovereign by design
Your data, your regulators, your rules.
Every service sits inside EU law. Infrastructure runs across European regions. Every layer - defensive, offensive, Agent reasoning - is EU-hosted by architecture, not as an option. That rule is not a preference, it is a hard architectural constraint.
Post-NIS2, post-DORA, EU sovereignty is procurement table stakes. We built Keelr so clearing your compliance team is a default, not a custom clause.
Prove your defence. Close the loop.
