Build security into the release, so vulnerabilities never reach production.
Application security is the work of finding and fixing flaws in your code and dependencies before they ship, through secure design, code review, SAST and DAST scanning, and closing the bug classes that keep landing on the OWASP Top 10.
Fastnexa folds these checks into your development pipeline so security becomes a step in the build, not a gate at the end that everyone resents. We triage findings by real exploitability rather than raw scanner counts, and pair each fix with guidance so your developers stop reintroducing the same issue. The outcome is fewer vulnerabilities reaching production and a team that writes safer code by habit. A fit for engineering orgs shipping fast that want to keep that speed without turning every release into a security liability.
A flaw that reaches production becomes a breach waiting to happen. Fastnexa builds application security into every stage of the development lifecycle so issues are caught while they are still cheap to fix. Our certified security experts combine automated scanning with thorough manual testing to find the vulnerabilities, logic flaws, and security weaknesses that attackers look for first.
Using OWASP methodologies, secure coding standards, and industry-leading tools, we perform SAST (static analysis), DAST (dynamic testing), IAST, and expert penetration testing to identify and remediate vulnerabilities. We embed security testing directly into your CI/CD pipelines, enabling shift-left security practices and DevSecOps adoption without slowing down your deployment cadence.

Common questions about our services, processes, and technologies.
Written by the engineers who do the work, and honest about the limits.
Held by the engineers who would run your engagement, not by the company in the abstract. Every one is verifiable with the body that issued it.
Offensive Security Certified Professional · Offensive Security
A 24-hour practical exam requiring live exploitation of unfamiliar machines. Widely treated as the baseline for hands-on penetration testers.
Advanced Web Application Penetration Tester · INE Security
Advanced web exploitation, covering the chained and logic-level flaws that automated scanners do not find.
Certified Web Exploitation Expert · Hack The Box
Practical web exploitation assessed by compromising live targets rather than by multiple choice.
Certified Ethical Hacker · EC-Council
Broad offensive security methodology. Frequently named directly in enterprise and public-sector procurement requirements.
Certified Defensive Security Analyst · Hack The Box
The defensive counterpart: detection engineering, log analysis and incident response, assessed hands-on.
Cybersecurity Analyst · CompTIA
Threat detection and behavioural analytics. Approved under the US DoD 8140 framework, which some contracts require.
Security Operations Analyst Associate · Microsoft
Operating Microsoft Sentinel and Defender, which is what matters if your estate is already on Microsoft 365 or Azure.
Huawei Certified ICT Associate, Security · Huawei
Network security on Huawei infrastructure, common in telco and enterprise networks outside North America.
PECB
Qualified to run a full external audit against the current 27001 revision, not merely to advise on it.
NIST Cybersecurity Framework Lead Auditor · PECB
Auditing against the updated NIST Cybersecurity Framework, which US federal supply chains increasingly ask for.
