DEFENDED vs Legacy Antivirus: A Fair Comparison

The Signature Problem

For decades, antivirus software relied on "signatures" — digital fingerprints of known viruses. If a file matched a signature, it was blocked. If not, it was allowed.

This worked well when there were 50 new viruses a day. Today, there are 500,000.

Fact: It takes less than 3 seconds for AI to generate a unique variant of malware that bypasses all signature-based filters.

Enter DEFENDED: Zero-Trust AI

DEFENDED takes a completely different approach. We don't just look at what a file looks like; we look at what it does.

Key Differences

| Feature | Legacy Antivirus | DEFENDED | |:---|:---|:---| | Detection Method | Database of known signatures | Behavioral AI Analysis | | New Threats | Updates required (hours/days) | Instant (Zero-Day) | | Performance | Heavy scanning | Zero-Load Architecture | | Privacy | Often uploads files to cloud | Local processing |

Conclusion

Signatures are still useful for catching old viruses, but for 2025 threats, you need behavior-based protection. That's why DEFENDED is built differently.
