We can work independently, as subcontractors, as a general contractor, at the direction of internal IT staff, or in a Rent-A-CIO functionality. We can manage a project from requirements to delivery, or just focus on a small part. We’re also available to help with assessments, testing, and second opinions when projects need to be set back on track.

Some of our areas of specialization include:

  • Digital Security (cryptography, TLS, system-hardening, penetration testing, protocol design, post-intrusion forensics, etc.)
  • Embedded and special-purpose systems development
  • Linux/BSD/AIX/Solaris systems configuration, administration, and automation (devops, Puppet, AFS/NFS/ZFS storage, etc.)
  • High-availability / redundancy (fault-resistant systems, clustering, auto-fail-over networks, database replication, etc.)
