Signal Secure About

Professional Security Installation

Signal Secure is a professional firm that does flawless security installation with industry-leading hardware and flat rate pricing.

Transparent Pricing

We offer luxury US-made security and home automation products with pricing competitive to what you find in the US. Our pricing is a flat rate - we never adjust the price tag based on the client! Our skilled technicians assess every job on its merits of hardware, travel, and hours it takes to do our job and to do it right.

Ex-Pat Friendly

As ex-pats ourselves, we have experienced firsthand the obstacles that arise when trying to get things done in a new country. In fact, our own experience led to the founding of Signal Secure! We wanted to create a company that we would trust to efficiently handle our own security projects! Our customers have found that we take great care to complete our projects right… and get them right the very first time!

Guaranteed Service

With Signal Secure, you have no fuss, no surprises, and no costly mistakes. We stand by our promise to always take full responsibility for our work - we resolve all issues at our own expense. This is our promise and guarantee to all Signal Secure customers.

Customer Testimonials

"Darien and his crew were very professional and installed our alarm in a timely manner. We have had the alarm system at Jaco Ropes Adventure Park for 3 years with no issues. Signal Secure has provided excellent customer service and I would highly recommend using them. It's nice to find a company that is willing to give great customer service in Costa Rica."

Pura vida!
