CMMC-ready
Aligned to CMMC 2.0, NIST 800-171 & FedRAMP for federal work

Northern Virginia is the federal-contracting capital of the country. Arlington alone holds the Pentagon and Amazon's HQ2, and the ring of Reston, Herndon, Tysons, and Chantilly is packed with defense, intelligence, and civilian-agency contractors, systems integrators, and the cybersecurity firms that serve them. Loudoun County's "Data Center Alley" carries a huge share of the world's internet traffic, and the US-East cloud region sits right in your backyard.
That world lives and dies by frameworks — CMMC 2.0 and NIST 800-171 for the defense supply chain, FISMA and NIST 800-53 for agency work, FedRAMP for cloud providers selling to government, and ITAR for controlled data. Most local IT shops can run a help desk; far fewer can carry the compliance weight. intSignal runs managed IT, a 24×7 security operation, cloud, and business communications under one roof, and produces the evidence assessors and contracting officers expect.
We support businesses across Arlington, Fairfax, and Loudoun counties and the wider DC metro — Reston, Tysons, McLean, Alexandria, Ashburn, and beyond. Senior engineers own your account, and because we operate our own geo-redundant infrastructure across three regions, we can place workloads where performance, cost, and compliance line up — and keep your recovery copy deliberately outside the crowded US-East region.
The services where being local actually changes the outcome — the region your data lives in, latency, on-site speed, the local climate, and a local phone number.
The region's work carries some of the strictest obligations in the country. We lead every engagement with the framework that governs yours.
Instead of juggling a helpdesk, a security firm, a cloud reseller, and a phone company, one team owns it all. When something breaks, there's one number to call and one team responsible — with real stake in keeping your business.
Real engineers own your account — people who speak CMMC, FISMA, and FedRAMP, not a tiered call center reading a runbook. You get the evidence and answers assessors and contracting officers actually ask for.
We run geo-redundant enterprise hosting across three regions, so we can place each workload where performance, cost, and compliance line up — public, private, or hybrid — instead of forcing everything into one cloud.
Remote-first for speed, with local technicians across Northern Virginia — and DR placed deliberately outside the crowded US-East region, so one regional outage doesn't take you down with it.
Tell us your stack and priorities — we return scope, ownership, and a plan, at no cost.
A complete outsourced IT department for Arlington businesses — or a co-managed extension of the team you already have.
A 24×7 security operation and the compliance work Arlington's regulated industries actually need — run by senior analysts, not an alert forwarder.
Public, private, or hybrid — placed where performance, cost, and compliance line up, on infrastructure we run across three regions.
Put data and AI to work — automation, analytics, and vision that improve how Arlington teams operate.
Replace an aging phone system with a cloud platform that travels with your team — voice, texting, video, and mobile, with AI built in.
The software that runs it all — our own security, network, and operations platforms, available managed or co-managed.
A short, low-risk path from first call to a running, monitored environment.
We map your Northern Virginia environment against the frameworks your contracts require — CMMC 2.0, NIST 800-171, FISMA, FedRAMP — and where CUI actually lives, at no cost.
A clear roadmap prioritized by what your contracts and auditors demand, including the System Security Plan and POA&M that federal work requires.
We secure and stabilize first — identity, access control, backups, endpoints, and continuous monitoring — and stand up the evidence assessors expect.
24×7 operations, a named team, and reviews that keep you continuously audit-ready for the next assessment.
On-site support across Arlington, Fairfax, and Loudoun counties — the wider Northern Virginia / DC metro, including the contractor and tech corridors.
Yes. We're remote-first for speed, but we dispatch engineers across Arlington, Fairfax, and Loudoun counties — Reston, Herndon, Tysons, McLean, Alexandria, and Ashburn — for hands-on work like installs, cabling, hardware, and new-office builds.
Yes — it's our most-requested Northern Virginia engagement. We assess against NIST 800-171, close the gaps, build your System Security Plan and POA&M, protect CUI, and run the ongoing monitoring assessors expect for CMMC 2.0 and DFARS.
Yes. For firms selling into the federal market, we support the FedRAMP journey — mapping and implementing the controls, producing the documentation, and running the continuous monitoring the program requires.
Yes. For regulated and controlled work we keep data in the US and give you documentation of exactly where it lives. We can place workloads near Data Center Alley for low latency, or deliberately elsewhere for resilience.
Yes. Our UCaaS platform is a full cloud phone system — calls, business texting, video meetings, a contact center, and business cellular — with AI transcription and IVR. We provision local 703 and 571 numbers, port your existing lines, and you can keep desk phones, go fully mobile, or both.
From small contractors and firms — roughly 20 to 500 staff — to their compliance-heavy suppliers, plus multi-site and growing companies. Our security operation and cloud scale up cleanly as you win work and add people.
