Where we operate 31 active mandates · 8 sectors

Sectors under mandate: Energy (6), Finance (7), Healthcare (5), Industry (4), Ports & logistics (3), Water (2), Defence (2), Public sector (2).

From a code review to the endpoint on a desk, we turn every blind spot into a signal you can act on, then into defence you can measure.

Turning uncertainty into a posture you control

  1. Weeks 1—2

    Map

    We inventory exposed assets, third-party dependencies and the attack paths that are genuinely walkable. Not a theoretical CVE list.

    • Dependency graph
    • Ranked attack paths

    240 assets fingerprinted on a median estate

  2. Weeks 3—5

    Break

    Red team, application testing and configuration review. We break what needs breaking, before an adversary does it without warning.

    • Red team narrative
    • Application findings
    • Configuration review

    14 critical paths closed per mandate, on average

  3. Week 6 onward

    • Response playbooks
    • Board-level metrics

    24/7 SOC watch, on a 15-minute triage commitment

FAQ

Questions? We have answers

Clients on Defend or Sovereign have a contractual 30-minute engagement commitment, around the clock. A crisis cell opens within the hour when triage warrants it.

Every engagement opens with a rules-of-engagement document setting scope, testing windows and stop conditions. On industrial networks we work passively by default, then against an isolated replica.

In France only, on SecNumCloud-qualified infrastructure. No data leaves the European Union, including for correlation and enrichment processing.

Yes. Watch exists for exactly that: visibility and qualified alerting without requiring an in-house security team. Most clients start there and move to Defend within twelve to eighteen months.

A three-page summary a chief executive can read, reproducible technical detail for every finding, a remediation plan ranked by effort and impact, and a re-test at ninety days included.
