Seiso empowers organizations to build resilient, well-governed security programs that go beyond audit-readiness. 

Leaders come to us asking: 

Who can help me get ready for my SOC 2, ISO 27001, or CMMC audit? 

Who can help me get cybersecurity in place without hiring a full team? 

Who can help me fix my audit findings so they don’t come back next year? 

Our Virtual Governance, Risk, and Compliance (vGRC) service combines technology and practitioner insight to give companies of all sizes a smarter path forward. You gain full access to multiple cybersecurity disciplines through this model, allowing you to confidently manage risk, protect assets, and maintain compliance—without the overhead of building a large internal team or investing in tools you don’t need. 

With Seiso, you gain a living, scalable security program that adapts as your business grows, supports strategic objectives, and translates compliance into a competitive advantage rather than just an obligation. 

What we deliver: 

Faster audit readiness and smoother audit experiences, reducing stress on your team 

Security and compliance programs that accelerate deals by demonstrating trust to customers 

Clear guidance on what to prioritize and what to avoid—so you don’t waste time or budget 

Tailored solutions that align security with your business goals, regulations, and technical environment 

Continuous oversight that keeps risks in check and compliance operating year-round 

The result? 

A security and compliance program that works, scales, and actually makes life easier for your team—whether your goal is to prepare for an audit, remediate findings, or strengthen governance for long-term growth. 

We’re proud of our 95% client retention rate and work hard daily to maintain our excellent reputation.

Trust in Seiso for the best results. It’s one reason why we were named Pittsburgh Tech Council's 2021 Start-Up Innovator of the Year, 2022 and 2023 Pittsburgh Business Times Best Places to Work.
