The flagship

Attack-Proven
Defence.

Continuous adversarial validation, EU-sovereign by design. Keelr attacks, Panthero defends, the loop never stops.

We attack your own systems, on your authorisation, the way a real attacker would. When we find something exploitable, we generate the fix, stage it on your pre-production environment, and attack it again to prove the exploit is dead. Only then do we propose promotion to production, where a human on your team gives the final go-ahead. This happens continuously, automatically, every hour of every day - not once a quarter in a PDF.

The loop, end-to-end

Five stages. Zero gaps.

Every exploit found goes through the same five-stage loop. Every remediation ships only after surviving adversarial re-testing. Every production change passes through a human gate.

Stage 1

Discover

Keelr runs continuous adversarial simulation against your authorised scope. Agents decide when, how, and what to probe - informed by propensity scoring across traffic patterns, CVE feeds, and Mission objective weight.

Stage 2

Validate

Keelr attempts a safe, non-destructive proof that the finding is genuinely exploitable. A theoretical match never reaches remediation. Only validated exploitability feeds the loop forward.

Stage 3

Ingest

The Loop's orchestration spine pipes the finding into Panthero with full context - target, exploit proof, severity on the shared 0-100 scale, remediation hints. The Defensive Agent picks it up.

Stage 4

Remediate

Panthero's Defensive Agent generates the fix (template or Agent-written code), deploys it to your staging environment, and simultaneously puts a compensating perimeter block in place so you are protected while the real fix is in flight.

Stage 5

Re-attack

Keelr reruns the exact exploit path against staging. If the path is closed, the fix is confirmed and proposed for production promotion. If still exploitable, the fix is rejected and the loop iterates.

The human gate

You approve prod

A human on your team reviews the confirmed fix and approves the production push. The autonomous loop stops at staging. Your change-control posture stays intact - even as the discovery, validation, and proposed remediation run without you.

What autonomy actually means

Autonomous to staging.
Human-approved for production.

"Fully autonomous" should never mean pushing code to your production blindly. The Loop runs without human intervention by default - up to the prod line. From there, a human on your team has the final word.

This resolves the liability, change-control, and customer-trust concerns that stop every other vendor from closing the loop. The autonomy lives in discovery, validation, and proposed remediation. The prod gate stays human-controlled, every time, no exceptions. And at any moment, you can pause or stop any Mission from the portal with one click.

You stay in control

  • Pause any Mission, any time
  • Stop any Mission entirely
  • Postpone next action by N hours
  • Blackout windows the Agent always respects
  • Optional approve-before-act on sensitive engagements
  • Production promotion always human-gated

The closed-loop proof

A fix is confirmed only after the exploit dies

Defence vendors ship fixes that look right on paper. We do not. A remediation stays in the "proposed" state until Keelr re-attacks the staged version and confirms the exploit path no longer works. This is what Attack-Proven Defence means - proven, not hoped for.

Fix confirmed

Keelr's re-attack fails against the staged version. The exploit path is closed. The Defensive Agent surfaces the fix as "ready to promote" - awaiting human approval for production.

Fix rejected

Keelr's re-attack still succeeds. The fix did not hold. The Agent iterates - new remediation, new staging deploy, new re-attack - until the exploit dies or the scope is escalated.

Protected meanwhile

The compensating defence put in place at stage 4 stays active until the confirmed fix promotes to production. You are blocked against the known exploit pattern at the edge, even while the real remediation is still being proven.

Why only we can sell this

A structural wedge, not a feature

We do not compete on category. We compete on structural impossibility.

Defensive incumbents cannot run offence

The big defensive vendors would need to acquire an offensive vendor and then integrate two companies, two cultures, and two product roadmaps. That is years of integration work for something that is a first-principles design choice here.

Offensive incumbents stop at findings

Continuous-pentesting vendors cannot own the remediation side without becoming a managed service and losing product economics. Their product ends at "here is the finding, good luck fixing it."

Only a purpose-built loop can credibly sell this

The Panthero + Keelr loop was designed as one system from day one. The orchestration spine is not a bolt-on integration - it is the product. Combined with our EU-sovereign posture, the wedge is: the only EU-sovereign, autonomous, closed-loop offence-to-defence platform. No US-cloud vendor can match it on the same terms post-Schrems II. No defence-only or offence-only vendor can match it at all.

EU-sovereign by design

Built for post-NIS2, post-DORA Europe

The loop does not just happen to run on EU servers. Every data contract, every evidence record, every Code Artifact, every re-attack proof is architected around European regulatory reality.

EU regions, multi-region

Infrastructure across Europe. Data residency, privacy, and compliance that European security teams expect by default. No transatlantic data transfers in the critical path.

NIS2 + DORA aligned

Continuous adversarial validation is exactly what NIS2 Art. 21 technical-and-organisational-measures asks for. The re-attack evidence stream is exactly what DORA threat-led penetration testing requires. Your auditor stops asking questions because the answers are already on the portal.

Sovereign posture

Romanian-EU tenancy by default on The Loop Government tier. Air-gap-compatible Agent deployment for sensitive scopes. Sovereignty is not a tier upsell - it is the default posture of the platform.
