Mission Ready Cyber Security for the UK’s Most Critical Assets

THE CHALLENGE

National security doesn’t get patch windows. Whether defending sovereign capabilities, safeguarding mission-critical systems, or protecting sensitive data in transit, the threat landscape has never been more complex or more aggressive.

Today’s defence and intelligence organisations must:

Operate at speed and scale

across federated environments, coalition networks, and contested domains.

Counter advanced persistent threats (APTs)

that use bespoke malware, living-off-the-land techniques, and long-term infiltration.

Secure multi-domain operations.

including cloud-hosted battle management systems, mobile edge platforms, and embedded ISR technologies.

Assure compliance with DSF, SyAPs, NIST 800-53, and the MOD’s evolving cyber policies

all under growing public and parliamentary scrutiny.

Legacy air gaps are dissolving. The adversary is persistent. The mission depends on getting cyber security right the first time.

When Mission Systems Meet Modern Threats

Mission Constraints

Secure-By-Isolation Designs

Systems never meant to be internet-connected now need remote support and coalition data flow.

TOP SECRET Environments

Protective marking, TSF protection profiles, classified enclaves.

Joint and Coalition Operations

Multiple nations, systems, and classification regimes.

Operational Pressures

Multi Domain Integration

Land, air, sea, space, and cyber must interoperate in near real time.

MODCloud, M365 IL3-IL5, and Agile Delivery

Data Centric Threat Models

Collision Point

Introducing remote access or cross domain transfer without robust policy enforcement can compromise an entire mission theatre.

Cloud adoption in secret environments creates complex assurance demands that can’t be solved by traditional perimeter thinking.

Trust must be policy-driven, identity-bound, and auditable across national boundaries.

How We Enable Secure Mission Success

 NCSC-Assured Risk Services for Defence & Intelligence

We’re one of the few consultancies accredited under the NCSC Assured Cyber Security Consultancy scheme, with experience supporting government and classified customers.

 

  • DSF & SyAP Readiness—risk models aligned with MOD assurance requirements, plus NIST 800-53, CAF, and JSP 604 policy overlays.
  • Threat-Informed Risk Assessments—Bow-Tie, MITRE ATT&CK, and kill-chain‑aligned views of system exposure across tactical and strategic levels.
  • Mission-Focused Engagements—we engage ops, not just CIS, understanding how cyber risk maps to operational risk.

Defence Grade Security Architecture

Our architects have designed Cross‑Domain Gateways (CDG) and Advanced Mobile Solutions (AMS). We understand the difference between “secure” and “assurable.”

 

  • Zero‑Trust by Default—identity-bound access, policy-based segmentation, and context-aware controls from the edge to the enterprise.
  • Secure Data Movement—diodes, guards, and CDGs built to NCSC and JSP specifications, deployed between OFFICIAL, SECRET, and COALITION networks.

 Advanced Security Operations Centre

You can’t defend what you can’t see. Our SOC was built to monitor highly sensitive environments with discretion, speed, and assurance.

 

  • Secure Telemetry Handling—accredited to handle OFFICIAL-SENSITIVE and SECRET data.
  • Defence-Aligned Playbooks—SOC workflows mapped to MOD kill chains, focusing on advanced actors, insider threats, and supply chain compromise.
  • Red Team Validated—playbooks tested through simulated attacks on real defence workloads, not just lab scenarios.

 Continuous Defence Loop

The threat moves fast. Our process moves faster.

  • Threat Intel Sprints—weekly cycles of intel review, rule tuning, and architecture validation.
  • Classified Threat Modelling—we maintain models of actor capability and intent specific to MOD and national security contexts.
  • Operational Metrics—mean time to detect, kill chain coverage, cyber mission impact, and board-level reporting that supports DSF assurance.
