“Teams always ask what makes Cyfendo different. Then they run one scan and find issues they never knew they had, with the fix already written.”

Questions before your first scan
My coding tool already scans. Why Cyfendo?
Your coding tool helps you ship faster. Cyfendo helps you ship securely. Its dedicated security engine uncovers vulnerabilities beyond routine scans, validates real exploit paths, and produces targeted patches backed by security and regression checks. Finding an issue is only the start. Cyfendo takes it through to a tested fix.
Will you keep my code?
Your code stays yours. Cloud scans run in isolated, temporary containers destroyed when the scan ends; only encrypted findings are retained. With Private Scan, your code never reaches Cyfendo. Your code is never used to train foundation models.
Will Cyfendo change my code?
Cyfendo does the security work. You keep control. It investigates vulnerabilities, prepares targeted patches, and tests them before review. Your team decides what gets merged—never Cyfendo.
What does it work with?
The code your business runs—whether written by developers, AI, or both. Cyfendo supports 10 language families, including Python, JavaScript/TypeScript, and Java. Connect a repository or upload your project. Keep your tools and workflow; add dedicated security.
