Westec Security no longer exists. Acquired by Interface Systems in 2012, the Westec brand has been fully absorbed into a commercial-only managed services company. If you’re searching for “Westec Security,” you’re either a former customer wondering what happened, or you found an old listing. Either way, here’s the full story — and far better options for home security in 2026.
What Happened to Westec Security? (Complete Timeline)
Westec’s story follows a pattern we’ve documented dozens of times on this site — a regional security company gets acquired, customers lose support, and the brand disappears. Here’s the full timeline:
| Year | Event | Impact on Customers |
|---|---|---|
| 1994 | Westec Security founded in Dallas, TX | Regional alarm dealer serving homes and businesses |
| 2000s | Westec grows through dealer network — pro install, long-term contracts | Proprietary equipment, 3-5 year contracts typical |
| 2012 | Interface Systems acquires Westec Security | Brand begins transition to commercial-only focus |
| 2013-2015 | Interface phases out Westec residential services | Home customers pushed to other providers or stuck in contracts |
| 2016-2026 | Westec brand fully retired — Interface focuses on enterprise | No residential support, website gone, brand dead |
Who Is Interface Systems?
Interface Systems is a managed services company focused exclusively on commercial and enterprise clients — think national restaurant chains, retail stores, and corporate campuses. They have zero residential presence.
| Detail | Interface Systems (2026) |
|---|---|
| Headquarters | St. Louis, Missouri |
| Focus | Commercial managed services (security, network, business intelligence) |
| Services | Multi-site video surveillance, interactive monitoring, POS integration, network management |
| Target clients | Retail chains, QSR restaurants, C-stores, enterprise campuses |
| Residential services | ❌ None — commercial only |
| Key capability | Virtual Guard — remote talk-down through cameras at commercial sites |
| Scale | 200,000+ managed locations across North America |
If you’re a homeowner: Interface Systems cannot help you. They don’t sell residential equipment, don’t offer home monitoring, and don’t support legacy Westec residential accounts. You need a modern DIY system — keep reading.
Why Westec’s Death Matters (The Acquisition Pattern)
Westec isn’t unique. The security industry has a pattern of acquisitions that leave residential customers stranded. Here’s the graveyard of absorbed brands:
| Dead Brand | Acquired By | Year | Residential Status |
|---|---|---|---|
| Westec Security | Interface Systems | 2012 | ❌ Discontinued |
| Protect America | Bankruptcy / shut down | 2023 | ❌ Dead |
| ASG Security | Guardian Protection | 2018 | ⚠️ Absorbed into Guardian |
| LiveWatch | Monitronics/Brinks | 2017 | ⚠️ Absorbed into Brinks |
| Security Networks | Monitronics/Brinks | 2016 | ⚠️ Absorbed into Brinks |
| NorthStar Alarm | Brinks Home | 2019 | ⚠️ Absorbed into Brinks |
| Cox Homelife | Discontinued by Cox | 2023 | ❌ Dead |
| AT&T Digital Life | Discontinued by AT&T | 2024 | ❌ Dead |
| Nest Secure | Discontinued by Google | 2020 | ❌ Dead |
The lesson is clear: Don’t build your home security on a company that might get acquired, change focus, or shut down residential services. Choose a provider where you own the equipment and can switch monitoring at any time — or one where home security is the entire business.
What Former Westec Customers Should Do Now
If you’re still on legacy Westec equipment — or worse, still paying a monthly fee to a monitoring company for an outdated Westec system — here’s your action plan:
| Step | Action | Details |
|---|---|---|
| 1 | Check your current contract | If you’re still paying monthly, find out who’s billing you. After the acquisition, some accounts were transferred to third-party monitoring companies. |
| 2 | Calculate what you’re paying | Legacy dealer monitoring typically costs $35-55/month — that’s $420-660/year for outdated technology with no smart home features. |
| 3 | Cancel your contract | If you’re month-to-month, cancel immediately. If under contract, check the ETF — it may be cheaper to pay the penalty than continue. |
| 4 | Don’t reuse the old equipment | Westec panels used older wireless frequencies and have no smart home capability. A clean switch to modern equipment is better and cheaper. |
| 5 | Switch to a modern DIY system | Install Abode, Ring, or SimpliSafe in under an hour — no installer needed, no contract, better technology. |
Cost Savings: Legacy Westec vs. Modern DIY
| Cost Category | Legacy Westec/Dealer | Abode (DIY) | Ring Alarm | SimpliSafe |
|---|---|---|---|---|
| Equipment | “Free” (built into contract) | $199 (Smart Security Kit) | $199 (8-piece kit) | $249 (Foundation kit) |
| Monthly monitoring | $35-55/mo | $0-20/mo | $0-20/mo | $19.99-29.99/mo |
| Contract | 36-60 months | None | None | None |
| 3-Year total | $1,260-1,980 | $199-919 | $199-919 | $969-1,329 |
| 5-Year total | $2,100-3,300 | $199-1,399 | $199-1,399 | $1,449-2,049 |
| Smart home | ❌ None | Google + Alexa + HomeKit | Alexa + limited Google | Alexa + Google (basic) |
| App control | ❌ None or basic | ✅ Full app | ✅ Full app | ✅ Full app |
| Geofencing | ❌ | ✅ | ✅ | ❌ |
| Camera integration | ❌ | ✅ Abode Cam 2 ($35) | ✅ Ring cameras | ✅ SimpliSafe cameras |
You could save $1,000-2,400 over 5 years by switching from legacy dealer monitoring to a modern DIY system — and get dramatically better technology in the process.
Best Westec Replacements in 2026
1. Abode — Best Overall (Our #1 Pick)
Abode is the best replacement for any legacy security system. It’s the only system that works with Google Home, Amazon Alexa, AND Apple HomeKit — plus Z-Wave, Zigbee, and Matter support for maximum smart home flexibility. Free self-monitoring forever, or add pro monitoring for $6-20/month with no contract.
Why Abode for former Westec customers: You went from a dealer-installed, contract-locked system to zero support. Abode is the opposite — you own everything, there’s no contract, and the company’s only business is home security. No acquisition risk. Visit goabode.com →
2. Ring Alarm — Best Budget Option
Ring Alarm offers the most affordable path to a complete, modern security system. Ring Protect Plus ($20/mo) covers the alarm AND unlimited Ring cameras — excellent value for the Amazon/Alexa household.
3. SimpliSafe — Easiest Transition
SimpliSafe is the closest to a traditional alarm experience — but with no contract and better technology. Their Fast Protect monitoring with video verification ensures faster police response.
Legacy Dealer Systems vs. Modern DIY: Feature Comparison
| Feature | Legacy Dealer (Westec-era) | Modern DIY (2026) |
|---|---|---|
| Installation | Professional install required ($0-199 + contract) | Self-install in 30-60 minutes |
| Equipment ownership | ❌ Company owns it | ✅ You own it |
| Contracts | 36-60 months with ETF | None — cancel anytime |
| Monthly cost | $35-55/month | $0-20/month |
| Smartphone app | ❌ or basic web portal | ✅ Full-featured iOS/Android |
| Smart home integration | ❌ | ✅ Google/Alexa/HomeKit |
| Geofencing auto-arm | ❌ | ✅ (Abode, Ring) |
| Camera integration | Separate CCTV system | Unified in one app |
| Crash & smash protection | ❌ | ✅ (cloud-based) |
| Communication | Landline (vulnerable to line cutting) | Cellular + Wi-Fi dual-path |
| Remote arm/disarm | ❌ Keypad only | ✅ App, voice, keypad, geofencing |
| Video verification | ❌ | ✅ (SimpliSafe Fast Protect) |
| If company is acquired | You’re stuck in a contract with a new company | Take your equipment to any monitoring service |
For Commercial/Business Security
If you’re actually looking for commercial security — the only thing Interface Systems (formerly Westec) still offers — here’s what to know:
| Interface Systems Service | What It Does | Best For |
|---|---|---|
| Virtual Guard | Remote talk-down through on-site cameras — operators challenge intruders in real time | Retail, warehouses, parking lots |
| Multi-site video | Centralized video surveillance across hundreds of locations | Restaurant chains, retail chains |
| Managed network | SD-WAN, POS connectivity, network monitoring | Multi-location businesses |
| Business intelligence | Traffic counting, queue management, operational analytics | Retail optimization |
For small business security (single location, small retail, office), Interface is overkill. Consider ADT Commercial or a local dealer using Alarm.com. For very small operations, Abode or Ring with commercial-grade cameras can work at a fraction of the cost.
Frequently Asked Questions
Is Westec Security still in business?
No. Westec was acquired by Interface Systems in 2012 and the brand is fully retired. Interface focuses exclusively on commercial managed services — they don’t serve residential customers at all.
Can I get residential security from Interface Systems?
No. Interface Systems is commercial-only (retail chains, enterprise, restaurants). For home security, we recommend Abode ($199 starter kit, no contract), Ring Alarm ($199, no contract), or SimpliSafe ($249, no contract). All install in under an hour.
I’m still paying for Westec monitoring — what should I do?
Your account was likely transferred to a third-party monitoring company after the acquisition. Check who’s billing you, review your contract terms, and cancel when possible. You’re likely paying $35-55/month for outdated technology with no smart features. A modern DIY system costs $0-20/month and is dramatically better.
Can I reuse my Westec equipment?
Technically, some legacy panels can be connected to third-party monitoring through services like Alarm Grid or Alarm Relay. But Westec-era equipment lacks smartphone control, smart home integration, cameras, and modern wireless protocols. For $199, a new Abode Smart Security Kit gives you vastly superior technology. The economics don’t favor keeping old equipment.
What happened to my Westec contract?
When Westec was acquired, customer contracts were typically assigned to Interface or a third-party monitoring partner. If you’re still under contract and it’s been more than 5 years since the original signing, you’re almost certainly on an auto-renewed term — check the cancellation guide for your options.
How do I avoid this happening again with a new system?
Choose a no-contract, equipment-you-own system. Abode, Ring, and SimpliSafe all let you cancel anytime. If any of them were acquired tomorrow, you’d keep your equipment and could switch to another monitoring service — unlike the Westec situation where customers were locked into contracts with no exit.

Quincy says
I wasn’t sure about this service and I am glad I found your review. I was under the impression that I could use this on my phone and I guess that is a no-go since they do not provide and app service. Bummer! I feel like this place would have been perfect for my family’s needs.
Taylor says
I didn’t need nor want an app. I don’t even know how to properly work a smart phone yet! That was the only downside for me with Westec and it wasn’t even an issue. I spoke to someone and they will be coming out next week to set me up. The prices were confusing but I guess they price you on the space/size of your house and what you need/want.
Barry says
How did it all go for you Taylor? I was debating on Westec but the app not being a feature was a bummer. Still, they were more in my price range than some other companies. I just want to hear from someone with recent experience so I know these online reviews are legit I have been reading.
Linda says
The only downside for me was the lack of an app but it has been mentioned that they plan to add one in down the road so I am hopeful. This far I have been impressed with Westec. The man I spoke to.. I believe his name was Tom, he was very sweet and understanding. I must have contacted them 3 times a day the first week I had the system installed. Very happy over all.
