### 2. [OffSec Penetration Testing Services](https://cybersectools.com/tools/offsec-penetration-testing-services)

OffSec provides manual penetration testing services aimed at organizations with mature security programs that require testing beyond standard vulnerability scans or checklist-based assessments. The service is delivered by OffSec's in-house team, which also develops Kali Linux and Exploit-DB and authors offensive security training content. Engagements have a minimum length of two weeks, averaging four weeks, and OffSec limits its client base to a small number of organizations per year, working with one customer at a time. Assessments focus on validating real-world exploitability of networks, systems, and applications through hands-on offensive testing rather than automated scanning. OffSec's advanced attack simulation offering builds custom attack labs based on information gathered directly from the client's team, then models and tests attack paths, including chained exploits, against a simulated version of the client's environment before executing tests in the live environment. This approach also supports cloud penetration testing for hybrid and cloud-native environments. OffSec also offers application security assessments that use manual and automated techniques, including reverse engineering, protocol analysis, protocol fuzzing, and custom attack development, to identify vulnerabilities in applications and supporting infrastructure. Clients include government agencies, financial institutions, healthcare organizations, manufacturing companies, and technology companies. Engagements begin with a direct conversation with a team member (not a salesperson) to determine fit, followed by defined rules of engagement, ongoing communication during testing, and a final report detailing findings and remediation recommendations.</description> <parameter name="summary">Manual, adversary-focused penetration testing services for mature security organizations
