Armour Communications

Armour Communications builds encrypted communications software — secure voice, instant messaging, conferencing, and file sharing — designed to run on off-the-shelf smartphones, tablets, and Windows desktops rather than requiring specialized hardened hardware. Its product line (Armour Recall, Armour Cloud, Armour Enterprise, Armour Connect, Armour Unity, Armour Bridge) lets government and enterprise customers deploy secure communications incrementally, using individual components or the full suite, which is a more flexible model than the single hardened-device approach used by some defense communications vendors.

Founded around 2015 and headquartered in Westminster, London, Armour holds ISO 27001 and Cyber Essentials Plus certifications and is approved for use up to Corporate Confidential, OFFICIAL-SENSITIVE, and NATO Restricted classification levels. That NCSC approval is a meaningful independent validation point in a category where vendor security claims are otherwise difficult to verify from the outside, and it underpins Armour’s customer base across UK defense, government, and financial services organizations.

For CISOs in regulated or government-adjacent sectors, Armour’s pitch is government-grade encrypted communications without the deployment friction of specialized secure hardware — employees keep using standard devices. The company is small (roughly two dozen employees) relative to the scale of the government and defense customers it serves, meaning organizations should weigh vendor continuity and long-term support capacity alongside the strength of its accreditations.
