Built by an MSP operator. For MSP operators.
Southern Sentinel Security exists because we saw the same problem you see every day: regulated SMBs need compliance-grade security, and most MSPs cannot cost-effectively build the infrastructure to deliver it.
A channel-exclusive managed security platform for MSPs.
We help MSPs serving regulated SMBs launch and operate a compliance-grade security practice — with stronger proof, lower adoption risk, and MSP-owned remediation. The platform productizes a service bundle already proven in delivery.
Nessus-backed vulnerability scanning. Cloud and identity security review. Compliance mapping across 7 frameworks. Audit-ready evidence generation. PSA-driven remediation workflow that keeps billable hours with the partner.
Go-to-market is 100% channel-only. You bring the client relationships. We provide the platform, compliance infrastructure, and proof layer you cannot cost-effectively build independently.

We do not sell to end-clients. We do not compete with our partners. Every client relationship belongs to the MSP.
Reports, portals, and client-facing deliverables carry your brand. Your clients see your MSP as the security authority.
Powered by Tenable Nessus Professional (OEM) — the same engine enterprise security teams recognize and auditors trust.
The people running your relationship — not your relationship’s queue.
Southern Sentinel is operated by experienced channel professionals who have spent their careers inside the MSP ecosystem. Combined, our partner-facing team brings 40+ years of channel experience to every relationship.
Gus Chiarello
Gus Chiarello is a 30-year channel veteran whose career has been defined by one enduring commitment: helping managed service providers build recurring revenue, scale their operations, and compete at the highest level. Beginning in infrastructure in 1994 and evolving deeply into cybersecurity over the last decade, he has founded and grown MSPs and MSSP practices, developed security practices, built national service networks, and mentored the sales and delivery teams that brought it all to life. At every stage of his career, what has motivated him most is not the technology itself, but the business owners and operators behind it — the MSP founders and MSSP leaders who take real risks to build something meaningful. That passion is what brought him to his role as VP of Sales at Southern Sentinel Security, where he works every day to help channel partners grow. He engages with MSPs and MSSPs not as a vendor chasing a sale, but as a peer who has navigated the same pressures of team building, service delivery, client acquisition, and margin management that define the channel ecosystem. His relationships in the industry are built on trust earned over decades, and on a reputation for showing up with real value — not a pitch. Gus also remains deeply committed to mentoring young professionals in the channel, investing the experience of 30 years back into the people and businesses shaping its future.
Clinton Gatewood
Clinton Gatewood has spent more than two decades in the MSP and partner ecosystem, specializing in channel strategy, partner program development, and data-driven partner acquisition. His experience spans working with leading channel-focused organizations, where he has helped build and optimize partner programs, define Ideal Partner Profiles (IPPs), and deliver actionable insights that drive measurable growth across partner networks. Clinton’s expertise sits at the intersection of channel data and execution—enabling vendors and partners to move beyond static partner lists into dynamic, insight-driven ecosystems. He has led initiatives focused on partner segmentation, recruitment, enablement, and performance optimization, often supporting executive stakeholders with data-backed strategies to improve partner productivity and alignment. At Southern Sentinel Security, Clinton leads Channel Data and Partner Strategy, helping MSPs, MSSPs, and channel organizations unlock new revenue streams through a 100% partner-first model. By combining offensive security services with a diagnostic-driven revenue engine, he works directly with partners to accelerate new logo acquisition, increase margins, and scale cybersecurity offerings without adding operational overhead.
The gap between what regulated SMBs need and what most MSPs can profitably deliver.
CMMC 2.0 Phase 1 is live. HIPAA enforcement is tightening. PCI DSS 4.0 is in effect. Regulated organizations need real security evidence — not checkbox compliance theater. And they are looking to their MSP to deliver it.
The problem is that building a credible, compliance-grade security practice from scratch requires licensing enterprise-grade scanning tools, building compliance mapping infrastructure, creating audit-ready deliverables, and integrating everything into an operational workflow. Most MSPs cannot justify that investment for the regulated SMB segment.
Southern Sentinel Security closes that gap. We built the infrastructure once so that every partner MSP can deliver enterprise-caliber security outcomes under their own brand — with per-user economics that make the practice profitable from the first client.
Not a cold-start product thesis.
4 partners, 14 live clients, 100% retention — now scaling. The delivery model being productized has been running with real MSP partners and real end-clients, with 40+ years of combined MSP channel leadership running the program.
