KERAUNOS is a private security practice built for organizations that cannot afford to be wrong. We operate at the intersection of offensive research, live monitoring, and incident response — quietly, precisely, and without exception.
Most security firms sell reassurance. We sell certainty. Every engagement begins from the assumption that you are already compromised — because statistically, in some small way, you probably are. Our work is to prove it, contain it, and close the door permanently.
Each engagement is scoped independently and staffed by operators who specialize in that discipline — not generalists rotating through a checklist.
Full-scope adversarial simulation across network, application, and physical vectors — executed the way a real intrusion would be, not the way a checklist expects it.
Continuous telemetry analysis across your infrastructure, correlated against active threat intelligence — watched by operators, not left to alert fatigue.
When something is already wrong, we contain first and explain later. Forensic reconstruction, eradication, and recovery — on a clock that matches the threat.
Zero-trust network design, identity governance, and infrastructure hardening — built into your systems at the design stage, not bolted on afterward.
Targeted research into actors, infrastructure, and emerging techniques relevant to your specific industry and exposure — not generic feed aggregation.
Audit-ready posture across SOC 2, ISO 27001, and sector-specific frameworks — treated as a byproduct of good security, not the goal of it.
Four stages. Each one produces a deliverable your team can act on — nothing waits until the end.
We map your real attack surface — not the one in your asset inventory. Shadow IT, forgotten subdomains, exposed credentials, third-party risk. This stage alone surfaces most of what gets exploited in the wild.
Our operators attempt to breach the environment using the same tooling and tradecraft active threat actors use against organizations like yours — documented in real time, not reconstructed afterward.
Findings are triaged by exploitability and business impact, not CVSS score alone. We work directly with your engineering team to close gaps — we don't just hand over a PDF and disappear.
Security posture decays the moment you stop checking it. Retained clients move into ongoing monitoring and periodic re-testing, so today's clean report doesn't become next quarter's blind spot.
The person who scopes your engagement is the person who runs it. No handoff to a junior team once the contract is signed.
We take a limited number of engagements at a time. Depth over volume — every client gets our senior bandwidth, not overflow capacity.
We are not incentivized to tell you your systems are fine. Our job is to find what's wrong before someone with worse intentions does.
Every report is written for the engineer who has to fix it, not the executive who has to read it — with both included.
Depth of coverage varies deliberately by domain. We concentrate expertise where the threat landscape is most active and most consequential for our clients, rather than claiming shallow competency everywhere.
Tell us about your environment. We respond to every serious inquiry within one business day, and we'll tell you plainly if we're not the right fit.
All inquiries are reviewed under NDA on request. We do not subcontract client work.
