What OPSWAT Can Do

The cPanel authentication bypass, PyTorch Lightning supply chain compromise, and UK Biobank data leak all share a common theme: attackers weaponize unpatched vulnerabilities and compromised credentials. OPSWAT’s MetaDefender Platform offers multi-scanning (30+ AV engines) for uploaded files, CDR (Content Disarm and Reconstruction) to strip active threats from documents, and Proactive DLP to prevent sensitive data exfiltration — directly applicable to the supply-chain and data-loss scenarios highlighted this week.
