// Network Security

Zero-trust networking, without the rip-and-replace.

Architecture review, segmentation, network detection & response (NDR), next-gen firewalls, IDS/IPS, and ZTNA rollouts — designed and operated by senior engineers. We work with your existing stack and reduce lateral movement risk by 80%.

// Capabilities

The full network stack — designed and operated.

Architecture Review

Senior-led review of your network topology, with segmentation and zero-trust design recommendations.

NDR (Network Detection & Response)

Darktrace, Vectra, ExtraHop, Corelight — we tune, operate, and integrate with your SOC.

Next-Gen Firewalls

Palo Alto, Fortinet, Check Point, Cisco — design, rule-base hardening, and ongoing optimization.

Zero-Trust Network Access (ZTNA)

Zscaler, Cloudflare Access, Netskope — phased rollout that replaces VPN without breaking the business.

Wireless Security

802.1X, rogue AP detection, and guest network isolation for enterprise Wi-Fi.

VPN & Remote Access

Replace legacy VPN with ZTNA, secure remote access, and MFA-enforced connectivity.

// The SENTINEL approach

Segmentation that actually ships.

Most segmentation projects stall. We deliver them. Our phased approach keeps the business running while we close attack paths in 90-day sprints.

  • Day 0: Network discovery, asset inventory, attack-path mapping.
  • Days 1–30: Quick wins: identity-based segmentation, jump hosts, MFA on admin paths.
  • Days 31–90: Microsegmentation rollout, NDR tuning, ZTNA pilot.
  • Day 90+: Continuous validation, purple-team exercises, and quarterly reviews.

Lateral movement risk reduction

Day 0 baseline100%
Day 30 (identity seg)55%
Day 60 (microseg)28%
Day 90 (ZTNA + NDR)18%
82% reduction in lateral movement risk within 90 days.
