What We Do

Risk Assessment

From system vulnerability scanning to data management procedures to weak passwords, we’ll identify where your biggest risks are hiding and recommend scalable strategies that will grow with your business.


Maintaining network security against unauthorized access is the heart of what we do. We’ll examine everything from firewalls, proxy services, access controls to your anti-virus software and auditing systems.

Hardware Management

Hardware lifecycle management, network design, firewall installations, staff training, threat monitoring – they all play a critical role in keeping you secure. We’ll procure, configure, implement and monitor these systems for you.

Business Compliance

If your business requires network security audits or for HIPAA, PCI, PHI or other data compliance, we’ll help you store your data in a way that is retrievable and highly secure. In addition, we specialize in mergers and acquisitions due diligence.
