Our penetration testing services simulate real-world attacks to identify and exploit vulnerabilities in your systems, providing actionable insights to strengthen your defenses.
At ReactiveZero, we provide thorough and goal-oriented penetration testing designed to uncover critical vulnerabilities across your digital assets. Our certified experts employ advanced techniques to simulate sophisticated attacks, giving you a clear understanding of your security posture and actionable recommendations to mitigate risks. For teams that need testing to run continuously between engagements, we also offer continuous, on-prem autonomous pentesting with R0.
The day markers below are indicative for a mid-sized web or infrastructure engagement; scope moves the dates, never the hand-overs.
We fix targets, test windows, escalation contacts and out-of-bounds systems in a signed rules-of-engagement before a single packet is sent.
Passive OSINT, DNS and certificate-transparency sweeps, then service fingerprinting; you confirm the asset list before anything is touched.
Hands-on testing against authentication, access control, injection and business logic; each confirmed flaw is reproduced and, if critical, reported the same day.
We chain findings to show real impact — privilege escalation, lateral movement, data reach — then remove every shell, account and file we created.
Findings register with CVSS scores, reproduction steps and fixes, plus a management summary; we walk your engineers through it live.
Once you have remediated, we re-run the original proof-of-concepts and issue a retest certificate you can share with auditors.
Assessing security of internal and external network infrastructure.
Identifying vulnerabilities in web applications like OWASP Top 10.
Testing iOS and Android applications for security flaws.
Evaluating security of cloud environments (AWS, Azure, GCP).
