INTERLOCK est. 1995
Houston MSP & MSSP

IT that runs like an in-house team without the headcount.

We are the Houston managed IT, cybersecurity, and private cloud partner that mid-market businesses trust to keep operations secure, predictable, and ready to scale. Engineer-run since 1995.

A senior engineer answers. No sales script, no ticket queue.

What we do

A complete IT department, delivered as one system.

Six capabilities engineered to interlock. Tap any tile to see how it works.

How we work

Engineered, not improvised.

Pick a principle to see what it means in practice.

Security is designed in, never bolted on.

MFA, EDR, SIEM, segmented networks, and a Zero Trust posture come standard. We have raised client Secure Scores from 40 percent to well past 90 percent, then held that line quarter after quarter.

The person who answers is the person who fixes it.

Every environment is designed from first principles by senior engineers holding CCIE, CCNP, and PCNSE. No swivel-chair tier-1 fixes that come back next month.

Your CFO sees a budget line, not a surprise.

Flat monthly pricing means we carry the technical and financial risk of keeping your stack healthy. No stack of project invoices every time something breaks.

Relationships that outlast technology cycles.

Our very first client, from a two-week engagement in 1995, is still a client today. That is not luck. It is the result of understanding the business first and bringing technology to it second.

Proof, not promises

Three decades of getting it right, on the record.

We were founded in 1995 by four engineers who believed technology should serve the business. Our first client is still our client. The numbers below are the byproduct of that discipline, not the pitch.

“The move to a private cloud gave our team the flexibility to work from anywhere without sacrificing performance. It simplified our IT and made the business much easier to support as we grow.”

Built for your world

Generic IT support does not survive a regulated, deadline-driven business.

Choose your industry to see where it usually hurts.

Downtime is measured in dollars per minute.

ERP, OT/IT convergence, and supplier portals have to talk reliably, and survive a ransomware event without halting shipments. We segment OT from IT, host ERP with documented recovery targets, and rehearse recovery so it is never improvised.

You are a target, and your auditors know it.

FINRA, SEC, and GLBA converge on one question: can you prove your data is secure, recoverable, and access-controlled? We bake those controls in and keep the evidence audit-ready.

Enterprise reliability, on a private school budget.

Every dollar on infrastructure is a dollar out of the classroom. We deliver FERPA-aware controls, cloud that scales with enrollment, and predictable costs the board can plan around.

Heavy applications. Mobile teams. Tight deadlines.

AutoCAD, Revit, Bluebeam, and Adobe are demanding and your files are massive. Private-cloud RDS runs them at full performance from anywhere, with centralized data and predictable per-seat costs.

Confidentiality is the product. A breach is the business.

Privilege, ABA rules, e-discovery, and retention make your IT a compliance instrument. We deliver encrypted document management, matter-based access, and a defensible retention posture.

FAQ

Questions we hear before the first call.

How does your flat monthly pricing work?

One predictable monthly fee covers proactive maintenance, monitoring, and support for the agreed scope. We carry the technical and financial risk, so your CFO sees a stable budget line instead of surprise invoices.

Do you replace our internal IT team or work with it?

Either model works. Many clients hand us everything. Others keep an internal lead and use our co-managed model, where we add senior architecture, 24/7 security operations, tooling, and surge capacity with a clear split of ownership.

What size companies do you work with?

Small to mid-market businesses that need enterprise-grade reliability without an enterprise-sized IT department, typically from around 25 to a few thousand employees.

How fast do you respond when something breaks?

Support is backed by defined SLAs, real engineers answer the phone, and 24/7 monitoring often catches issues before your team notices. After-hours coverage respects court calendars, deal cycles, and production windows.

Can you help with cybersecurity and compliance?

Yes. As an MSSP we deploy EDR, SIEM, MFA, and awareness training, and align controls to frameworks like FINRA, SEC, GLBA, and FERPA depending on your industry.
