Zero Trust Security Solutions

Zero Trust is an architecture, not a single product. NIST SP 800-207 defines it as moving defenses from network perimeters to users, assets, and resources. Products in this space typically cover access (ZTNA), identity, device posture, and segmentation.

Problems this category addresses

  • Over-broad VPN access to internal networks
  • Lateral movement after a single compromised account
  • Inconsistent access policies for remote and on-site staff

Deployment and administration

  • Map the applications and users in scope before choosing tools.
  • Use the CISA Zero Trust Maturity Model to plan phases.
  • Expect Zero Trust to involve multiple products working together.

Integration considerations

  • Identity providers (SSO, MFA)
  • Endpoint posture tools
  • SIEM and SOAR

Best-fit use cases

  • Replacing or reducing VPN reliance
  • Securing contractor access
  • Segmenting sensitive systems

Questions to ask during a demo

  1. Which Zero Trust pillars does your product cover, and which do we need elsewhere?
  2. How do you protect applications that are not web-based?
  3. What does day-to-day administration look like after the initial rollout?
  4. How are policy exceptions requested, approved, and audited?
  5. What happens to protection if an endpoint loses connectivity to the management console?
  6. Which operating systems and versions are supported today, in writing?
  7. How is pricing structured, and what is excluded from the quoted price?
