Attomus combines cybersecurity, programme delivery, and specialist services in one focused offer for organisations where trust and discretion matter.
JOSCAR registered and built for higher-trust work
JOSCAR is the Joint Supply Chain Accreditation Register used by major aerospace, defence, and security buyers to pre-qualify suppliers. Registration confirms Attomus has passed central assessment of compliance, cybersecurity, and financial standing. Most of the team hold UK or NATO national security vetting. Our principals average over two decades of experience across government, defence, and regulated enterprise.
When the requirement is harder to resource or handle through a general supplier
Attomus is typically brought in by organisations that already have internal security or delivery capability but face a requirement they cannot resource quickly enough, or where the sensitivity of the work demands a level of vetting, discretion, and judgement that a general supplier cannot meet. Our clients tend to operate under meaningful scrutiny, whether regulatory, parliamentary, or reputational, and treat engagement handling as part of the requirement, not an afterthought.
