Engagement frame

Commercial transparency without promising timelines that depend on scope not yet closed.

Proposal5–10 business days after receiving complete scope information
Typical window2–4 weeks for scoped web/API pentests; deep dives depend on surface
DeliverablesTechnical report + executive summary; readout (optional) and retest per SOW

Operational trust

We work with teams that already take risk seriously — without invented logo marketing.

  • Discretion by default

    No public client portfolio on the web. Cases and logos only with explicit authorization.

  • Scope always in writing

    Assets, windows, exclusions, and engagement rules agreed before invasive activity.

  • Credentials under control

    Operator certifications and CVs are shared in advanced commercial phases or under NDA, per procurement process.
