Cyber security solutions for defence and security operations

The cyber security threat for defence

Defence organisations operate under constant pressure. Nation-state attacks, ransomware, supply chain compromise, and insider risks threaten operational readiness. At the same time, compliance frameworks such as NIS2, GDPR, Cyber Essentials Plus, CMMC, and the NCSC CAF demand demonstrable security controls.

For defence operations, a cyber security breach is more than an IT failure, it endangers missions, compromises classified intelligence and undermines trust with allies and suppliers. Cyber security for defence must therefore secure systems, people, and data while maintaining operational agility.

We help you stay ahead of these risks by delivering tailored defence cyber security solutions that protect systems, people, and data.

Navigating defence compliance frameworks

Defence compliance requirements are stringent, but we help you simplify them with security controls built to meet global defence and government standards.

In defence, we know compliance is non-negotiable. Regulations span across geographies:

Cyber Essentials Plus

Proves core security controls for MoD suppliers.

NCSC CAF

Assesses and strengthens cyber resilience.

NIS2 Directive

Sets security rules for essential services.

GDPR

Protects personal and operational data.

CMMC

Certifies cyber maturity for defence contractors.

SecurEnvoy solutions support defence cyber security demands and align directly with these frameworks, helping defence organisations simplify compliance while maintaining security. Our solutions reduce audit complexity, ensure accountability, and provide proof of control in the most demanding environments.

Cyber security in defence FAQs

Why is multi-factor authentication critical in defence cyber security?

Defence organisations handle highly sensitive systems and classified data. MFA for defence ensures that only authorised users gain access, reducing risks from stolen credentials and insider threats.

How does access management strengthen defence cyber security?

By defining who can access which systems and when, Access Management for defence prevents lateral movement in case of breach and supports compliance with frameworks like Cyber Essentials Plus and NCSC CAF.

Which compliance standards affect cyber security in defence?

Defence organisations must align with NIS2, GDPR, CMMC, NIST, and Cyber Essentials Plus. SecurEnvoy supports CMMC compliance MFA and NIS2 compliance defence requirements.

Why is on-premise or air-gapped MFA important for defence organisations?

Many defence cyber security contexts require offline or isolated systems. SecurEnvoy provides air-gapped MFA solutions to secure restricted, high-security environments.

Can MFA protect against nation-state threats in defence?

Yes. MFA for defence significantly reduces risks from credential-based attacks, one of the most common tactics used by nation-state actors.
