Principal-led offensive security
Defensible security assessments backed by a verifiable audit trail. No guesswork, no automated fluff. Just the exact paths an attacker would take, fully proven before it reaches your desk.
Every report signed by a certified pentester
Services
Every service runs through the same validation pipeline, probe, reproduce, baseline, report.
Full path tracing from Domain User to Domain Admin. CRTE-certified attack paths, Kerberos abuse, ACL chain escalation, each step reproduced and evidenced.
Privilege escalation and pipeline abuse across AWS, Azure and GCP, validated against your real identity model, not a generic benchmark.
Static and dynamic analysis of web, API and native mobile targets. Scanner output is a starting point, never a finding.
A direct line to a principal for triage, containment guidance and forensically sound evidence preservation, no ticket queue in between.
How it works
The same validation pipeline runs on every engagement, from a single web application to a full Active Directory estate. Each gate produces artifacts you keep.
Rules of engagement agreed in writing before anything touches your environment, targets, windows, data handling, legal sign-off.
Signed authorization
The attack surface is enumerated strictly inside scope. Coverage is measured, not assumed.
Trust-boundary map
Every candidate finding is probed, its impact reproduced, and compared against a baseline differential. False positives are demoted here.
Proof artifacts
Findings ship with evidence attached, mapped to MITRE ATT&CK, with actionable remediation, then a retest verifies the fix.
Evidence-backed report
The attack path
Findings are not a flat list. They chain. The engagement graph shows exactly how, and where a fix breaks the chain.

Human-on-the-Loop
Automation runs at machine speed. At every critical decision point, a human principal reviews, decides and signs before anything proceeds.
Every engagement is mapped as a live graph: the attacker's entry point, the weakness classes found (OWASP 2025), and the hosts they reach. Edges are validated routes, not guesses, and colors carry severity at a glance.
Each node shows how many of its findings were corroborated with evidence. A finding that could not be reproduced stays visibly uncorroborated, it is never silently promoted into the report.
Automation maps the surface and runs the safe probes. At every critical decision point, anything with real impact on your environment, the principal reviews, decides and signs before it proceeds. Machine speed, human judgment.

Every engagement is led personally by Yaniv Avisror, and behind him stands a senior bench: offensive-security specialists and CISO-level advisors who join projects as the scope requires. No juniors, no outsourcing of judgment, and the person who tests is the person who signs.
FAQ
Yaniv Avisror (CRTE), the founder and principal, leads every engagement directly. Depending on scope, senior offensive-security specialists and CISO-level advisors accompany the project. There are no juniors on the team, and the principal signs off on every finding.
No. Scanner output is treated as a lead, never a finding. Every candidate is actively validated: the probe is executed, the impact reproduced, and the result compared against a baseline differential. Anything that cannot be proven is demoted, not reported.
An evidence-backed report: each finding with reproduction steps, proof artifacts, a MITRE ATT&CK mapping, severity in your context, and remediation guidance your defenders can act on, followed by a retest window to verify fixes closed the path.
Engagements are scope-locked with zero data egress. Evidence is captured under data-handling rules agreed in writing before testing starts, and it never leaves the agreed boundary.
It depends on the surface: a focused web application differs from a full Active Directory estate. Scope is defined first, and you get a fixed timeline before anything starts. Most engagements run one to three weeks.
