Nation-state APTs
Advanced persistent threats establish quiet, long-term footholds for espionage. We hunt for the low-and-slow tradecraft that signature tools miss entirely.
Government & Public Sector
Defending the public's trust and data.
Federal agencies, state and local governments, and their contractors are squarely in the sights of nation-state adversaries — and they hold the citizen data and critical services a nation depends on. S-Security delivers FedRAMP-aligned, CMMC-ready defense built for the highest-stakes threat model there is.
Threat landscape
Adversaries with patience and budget
Government targets attract the most capable attackers — state-sponsored groups pursuing espionage, disruption, and long-term access.
Critical infrastructure
Utilities, transit, and emergency services are tempting disruption targets. We extend monitoring across IT and the operational systems that run public infrastructure.
Citizen data exposure
Tax, benefits, and records systems hold deeply personal data on millions. Data-centric monitoring stops the mass exfiltration that fuels identity fraud at scale.
Ransomware on agencies
County and municipal governments are favorite ransomware targets. Early detection of lateral movement keeps services like 911 and permitting online.
Supply-chain compromise
Software and contractor supply chains are a proven path into government networks. We watch for the trusted-update and third-party abuse that bypasses the perimeter.
Disinformation & election threats
Election and public-facing systems face both intrusion and influence operations. We harden these systems and monitor for the tampering that erodes public trust.
Compliance
Built to the federal bar
Public-sector security runs on rigorous frameworks and authorizations. We design to them from day one and produce the artifacts assessors expect.
- FedRAMP — control implementation and continuous monitoring aligned to Moderate and High baselines for cloud services.
- CMMC 2.0 — readiness and managed controls for defense contractors handling CUI, mapped to NIST 800-171.
- NIST 800-53 & the RMF — full control families with documented assessment evidence for ATO support.
- FISMA, CJIS, and StateRAMP — coverage for federal, criminal-justice, and state cloud requirements.

Scenario
A quiet foothold, exposed in week two
A state agency engaged S-Security after a routine assessment. Within two weeks our threat hunters found a dormant web shell on an internet-facing server — a state-sponsored actor's patient foothold, planted months earlier and waiting.
We traced every action the implant had taken, confirmed no citizen data had been exfiltrated, removed the access, and closed the vulnerable edge service. The agency received a full forensic report suitable for its oversight board and federal partners.

"S-Security found a nation-state implant two other vendors walked right past. They report our posture in plain English the oversight board can act on, and our ATO work moves faster because of it."

FAQ
Government security questions
Are your services FedRAMP and CMMC aligned?
Yes. We implement controls aligned to FedRAMP Moderate and High baselines, support CMMC 2.0 readiness for defense contractors, and map everything to NIST 800-53 and 800-171 so your assessments and ATO efforts move faster.
Can you defend against nation-state attackers specifically?
It's a core focus. Our threat hunters specialize in the low-and-slow tradecraft of APT groups, our intelligence team tracks state-sponsored actors, and our detection emphasizes the subtle behavioral signals these adversaries leave rather than relying on signatures.
Do you support state and local governments, not just federal?
Absolutely. We work with state agencies, counties, and municipalities, including coverage for StateRAMP and CJIS requirements, and we tailor programs to the budget and staffing realities of local government.
Can you monitor operational technology behind critical infrastructure?
Yes. We extend visibility across both IT and OT environments — water, transit, and emergency systems — using passive monitoring that respects the availability and safety constraints of operational networks.
