Our engineers write secure code, not just scan for problems after. We understand OWASP vulnerabilities, authentication design, and the coding patterns that prevent issues from appearing in the first place. You get developers who build security in, not consultants who hand you a findings report.
Secure Software Development From the Start
Embed secure coding practices into your development process so security stops being the thing that slows releases or fails audits.

Trusted and top rated tech team
Security that ships with the code
Security gets treated as a final checkbox — then pen tests find OWASP vulnerabilities, audits surface gaps, and your team scrambles to fix what should have been prevented. We embed secure coding practices into development so vulnerabilities get caught early, remediation doesn’t block releases, and your code passes security reviews the first time.
Our capabilities include:
- Secure coding standards and code reviews
- OWASP vulnerability prevention and remediation
- Threat modeling and security architecture
- Pen test finding remediation
- Input validation and authentication design
- Security training and developer enablement
Who we support
Scanners find vulnerabilities, but someone still has to write code that doesn’t have them. We work with teams that need secure coding expertise, not just more tools.
Teams That Keep Failing Pen Tests
Your annual pen test comes back with the same OWASP findings — SQL injection, XSS, broken authentication. You patch the specific issues, but the patterns repeat because developers aren't trained to prevent them in the first place.
Companies Fixing Insecure Codebases
Your codebase grew quickly, and security took a backseat. Now it’s full of input validation shortcuts, hardcoded credentials, and authentication gaps. You need someone to fix it, not just scan it.
Teams Preparing for Security Audits
Your SOC 2 or HIPAA audit is coming and your code needs to pass review. You need secure coding practices implemented and documented, not just a promise to add scanning later.

Secure development capabilities for production code
Secure Coding Standards
Establish coding guidelines that prevent common vulnerabilities so developers write secure code by default, not by accident.
Threat Modeling & Security Design
Identify attack surfaces and security requirements during design so architecture decisions account for threats before coding starts.
OWASP Vulnerability Remediation
Fix injection, XSS, authentication flaws, and other OWASP Top 10 issues in existing code with patterns that prevent recurrence.
Security Code Reviews
Review code for security issues that automated scanners miss, including logic flaws, access control gaps, and unsafe data handling.
Input Validation & Authentication
Design validation, sanitization, and authentication flows that protect against injection attacks and unauthorized access.
Security Training & Enablement
Train your developers to recognize and prevent security issues so secure coding becomes habit, not afterthought.

FAQs about our secure software development
How is this different from DevSecOps?
DevSecOps automates scanning in your pipeline to catch issues early. Secure development trains your team to write code that has fewer vulnerabilities to begin with. They work together — we help with both.
Can you fix findings from our pen test?
Yes. We remediate specific vulnerabilities and address the underlying patterns that caused them so the same issues don’t reappear in future code.
Do you train our developers?
Yes. We provide secure coding training tailored to your stack and the vulnerabilities common in your codebase. The goal is making secure coding habitual, not a checklist.
What if our codebase is already insecure?
We audit existing code, prioritize vulnerabilities by risk, and remediate systematically. Legacy security debt doesn’t get fixed overnight, but it does get fixed.
How do you handle threat modeling?
We identify assets, entry points, and potential attack vectors during design using frameworks like STRIDE. Threats get documented and addressed before code is written.
Can you help us pass a security audit?
We implement secure coding practices, remediate vulnerabilities, and document controls. When auditors review your code, they find evidence of security built in — not bolted on.
