Haidera Labs
Shows how this page protects you: its security headers, what it loads, and what it stores. Start a project
A dark board-formed concrete room. One narrow slot in the far wall lets in a blade of daylight.

Software that holds.

HaideraLabs designs, builds and hardens web and mobile products. Then we attack them, before anyone else does.

Made in Ankara, for the people who will depend on it.

How we work

  1. We build it.

    Design, front end, back end, admin. One team, one codebase per platform.

  2. Then we try to break it.

    Threat model, static analysis with Semgrep, dynamic scans with OWASP ZAP, and a person reading the code with bad intentions.

  3. We fix what we find.

    Broken access control, IDOR, token handling, privilege escalation. Each fix comes with a note on why it works.

  4. Then we scan again. Only then does it ship.

    Re-scan, regression tests, and a written report you keep, with findings scored in CVSS v4.0.

  • Diwan Türkiye home screen: an İkamet tracker showing 27 days left before the residence permit expires.
  • The İkamet renewal guide for students, verified against Law No. 6458, with the required documents checklist.
  • A list of Ankara's universities inside the app's directory.

Diwan Türkiye

Free on iOS and Android, for anyone living anywhere in Türkiye: every paper for your residence permit, the fees and payment codes, emergency help, universities, and a community that answers.

In Arabic, English and Turkish. Its assistant answers only from dated, cited sources. When it can't, it sends you to the office that can.

What we build

Security review
For software you already have. Threat model, scans, fixes, a re-scan, and a written report scored with CVSS v4.0.
