Frequently Asked Questions

Common questions about VLN security services

Automated tools catch ~40% of vulnerabilities. Human experts catch logic errors, business logic flaws, and context-specific issues that tools miss. 60% of exploits come from these 'invisible' bugs that only experienced auditors can find.
We sign NDAs for every engagement. Our reputation depends on trust. We've worked with government agencies and legal teams - our ethics are our business. Plus, we're in this for the long haul, not a quick buck.
No one can guarantee 100% security - anyone who claims otherwise is lying. What we guarantee: thorough review, honest findings, and actionable fixes. Our track record: 0 post-audit exploits on contracts where clients implemented our recommendations.
If an exploit occurs in code we audited AND it's a vulnerability we missed, we'll provide free forensic investigation. But in 12 years, this has never happened to a client who implemented our fixes.
