Vulnerabilities reported through standard coordinated disclosure channels. Engineering team reviews, validates, and addresses on a defined response timeline.
Platform updates and threat intelligence updates push automatically across deployed Shield instances. Customers and partners notified of significant releases.

Cybersecurity vendors love checkbox claims. We’re honest about ours. Shield does not process GDPR or HIPAA-regulated data as part of its operation, so those frameworks don’t apply to it. Shield does not currently hold FedRAMP, GSA Schedule, SOC 2, or ISO 27001 certifications. What we offer instead: evidence-backed protection your auditors can verify.
If your buyer needs a specific certification, ask us directly. We’d rather answer the question honestly than overpromise on a roadmap.
We’re building approved customer narratives across MSSP, OT, and federal verticals. Approved customer stories are coming online soon. In the meantime, we’ll connect you with reference customers directly.
External validation that strengthens the procurement conversation.
