RSI Security is a cybersecurity and compliance partner for organizations in highly regulated industries. We work with healthcare systems, financial institutions, government contractors, defense industrial base (DIB) organizations, technology companies, and critical infrastructure providers including maritime and energy sectors, where RSI holds experience few firms in this space can match.
What sets RSI apart is breadth under one roof. We hold QSA, ASV, CMMC C3PAO, and HITRUST CSF Assessor certifications simultaneously, a combination most compliance firms don't carry together. That means clients don't need to coordinate separate vendors for PCI assessment, CMMC certification, HITRUST validation, and incident forensics. One team, one point of accountability, across the full framework landscape.
We support organizations across CMMC, FedRAMP-adjacent federal requirements, HIPAA, HITRUST, PCI DSS, SOC 1 and SOC 2, ISO 27001, NIST 800-171, DFARS, GDPR, and emerging AI governance frameworks including ISO 42001.
Our model combines three things competitors typically offer separately:
— Compliance advisory and assessment (gap analysis, control mapping, audit preparation)
— Technical security services (penetration testing, vulnerability assessment, social engineering testing, architecture review)
Most compliance-focused firms are audit-only. Most security operations firms don't hold assessor certifications. RSI does both, which means the same team that identifies a gap can also help close it, instead of handing clients off to a different vendor for remediation.
We work with organizations from mid-market to enterprise, with engagement models built around partnership rather than one-time transactions: from a single assessment through long-term continuous security maturity programs.
Independent, unbiased assessments. A team that explains frameworks in plain language instead of jargon, because clarity, not complexity, is the standard we hold ourselves to.
