The Best TSCM Bug Sweeping Companies in LA: 2026 Report

How 11 counter-surveillance firms compare for homes, boardrooms, vehicles, and legal matters across Los Angeles County.

From April to September 2026, our research team built this ranking using a methodology that scores 11 TSCM and bug sweep providers serving Los Angeles: dedicated counter-surveillance firms, national security companies, and licensed local private investigation agencies. Each firm was evaluated on seven weighted criteria, including documented case history, technical depth, LA coverage, and public review scores.

This report breaks down how each company compares on credentials, coverage, pricing, and client feedback, and which firms stand out for corporate, residential, vehicle, digital, and legal work. All information reflects publicly available sources such as company websites and online reviews rather than private quotes, so actual pricing and availability will vary.

We reviewed 11 firms that serve the Los Angeles market between April and September 2026 and scored each one on seven weighted criteria:

Comparison Table: TSCM Companies in Los Angeles

1. Bugged

Bugged has worked exclusively in TSCM, bug sweeps, and counter-surveillance since 1986. Its best-known Los Angeles engagement is the Henry C. Yuen "patent terrorist" matter, an espionage case tied to the former TV Guide and Gemstar building on Hollywood Boulevard, where surveillance devices were located and removed. Founder Michael Peros trained under former CIA technical surveillance expert Glenn Whidden and has spoken at DEF CON on illegal wiretapping.

The firm's CyberBug TSCM service combines a physical sweep with mobile, network, and digital forensics, so one engagement can cover a residence, an office, vehicles, and the devices that connect them. Bugged was also the first company in the world to launch TSCM services on the World Wide Web. Bugged reports more than 30,000 clients. Its headquarters is in Florida, so Los Angeles work is a deployment rather than a local drive, pricing is quote-only and sits at the top of the market, and its public review count is small.

2. Murray Associates

Murray Associates was founded in 1978 by Kevin D. Murray, who previously served as International Director of Electronic Countermeasures for Pinkerton's. The firm works only in counter-surveillance and counterespionage consulting, reports more than 4,000 completed assignments, and does not resell equipment, so its recommendations are independent. Murray holds the CPP, CISM, CFE, and CDPSE credentials.

It is also one of the few firms that publishes cost guidance, citing a typical home sweep at $1,500 to $6,000 and corporate programs at $15,000 to $30,000 per quarter. The trade-off for LA buyers is distance. The firm is based in the New York metro area, so every Los Angeles job is a fly-in, and its public case documentation is lighter than its tenure would suggest.

3. ComSec LLC

ComSec is a Virginia Beach firm founded in 2007 by J.D. LeaSure, who built its practice around what the company calls Cyber TSCM: finding eavesdropping devices that send data over Wi-Fi, Bluetooth, or cellular networks. It keeps a downtown Los Angeles field office, says it can usually be onsite within 24 to 72 hours of a finalized quote, and does not charge extra for evenings or weekends.

ComSec also designs and sells its own TSCM equipment, including IMSI catcher detectors, which gives it real technical depth. Its published finds, such as GSM bugs in executive offices and laser microphones aimed at boardrooms, are described without client names, and it has no marquee cases on the public record. It holds an A+ BBB rating.

4. LaSorsa & Associates

LaSorsa & Associates was founded by Joseph A. LaSorsa, a former U.S. Secret Service agent who served on the Presidential Protection Detail. The company has technicians in Los Angeles, San Diego, and San Francisco, offers free and discreet consultations, and has been featured on CNN, MSNBC, and Fox News. LaSorsa has also testified as an expert witness on technical surveillance at a congressional hearing.

Bug sweeps are one part of a broader executive protection, training, and investigations business, so clients are not hiring a TSCM-only specialist. The firm is headquartered in North Carolina, publishes no pricing, and has no review score specific to its sweep work.

5. LA Intelligence

LA Intelligence is a Beverly Hills private investigation firm with two Wilshire Boulevard offices and a 5.0 rating on Yelp. Its team includes investigators with federal law enforcement and intelligence backgrounds, and its sweep clients include celebrities, politicians, and high-net-worth families who want fast, discreet help close to home. It received a Yelp award in 2018.

Bug sweeps are one of more than a dozen services, and most of its reviews describe general investigations rather than TSCM. The firm has operated under its current name since 2011, publishes no pricing, and has little public record of landmark counter-surveillance cases.

6. USPA Nationwide Security

USPA Nationwide Security has performed electronic surveillance sweeps since 2005 and is one of the largest protective services companies on this list, with a reported network of more than 5,000 contractors and 24/7 dispatch. Its Los Angeles sweeps are led by former Navy SEALs, Army Rangers, and retired intelligence personnel, and it has been featured in Forbes and on Crime Stories with Nancy Grace.

TSCM is a specialty line inside a company built mainly on guard services, fire watch, and executive protection. Its 4.9 Google rating covers the whole company rather than sweep work, pricing is quote-only, and there is little public documentation of specific devices it has found.

7. Empire Pacific Investigative Services

Empire Pacific Investigative Services (EPIS) was founded in 1993 by three retired U.S. federal special agents and works out of West Hollywood, minutes from Beverly Hills, Hollywood, and Century City. Its TSCM offering goes past one-time sweeps to include in-place monitoring, wireless intrusion detection, and randomly scheduled follow-up sweeps, which suits clients who need ongoing coverage.

EPIS is a general investigations firm first, and TSCM is one of many service lines. It lists no counter-surveillance awards or credentials, publishes no pricing, and focuses on the LA metro rather than deploying to other states.

8. Sunset Blvd. Investigations

Sunset Blvd. Investigations is a downtown Los Angeles firm co-founded by Steve Polak and Randy Petee, retired detectives from the LAPD and the Los Angeles County Sheriff's Department. Its TSCM work is handled by an in-house specialist with more than 35 years of counter-surveillance experience, and the founders work cases personally. Many of its testimonials come from attorneys.

It is a small boutique with weekday office hours, which limits after-hours mobilization and multi-site jobs. It covers Los Angeles and Orange County rather than following clients nationally, and its public record centers on investigations rather than documented counter-surveillance finds.

9. West Coast Bug Sweep

West Coast Bug Sweep is a California-licensed private investigation agency (PI# 27041) that focuses only on TSCM, which sets it apart from the many generalists in the region. Led by president Reymundo "Ernie" Mireles, the team handles residential, business, and vehicle sweeps plus cyber checks for compromised Wi-Fi, and each inspection ends with documented findings a client can bring to an attorney or the police.

The firm is regional, covering Los Angeles, Orange, San Diego, Riverside, and Ventura counties from an Inland Empire base. It lists no awards, has a small number of public reviews, and has little published case history for high-stakes environments.

10. Discreet Services

Discreet Services is a veteran-owned investigation firm founded by Jason Beberniss, a U.S. Army veteran and Bronze Star recipient. Its sweep teams are sized to the location and threat, and they work with Research Electronics International RF equipment, an Orion non-linear junction detector, and FLIR thermal imaging. Free consultations make it easy to talk through a concern first.

The company is based in Phoenix and sends teams to Los Angeles rather than keeping a local office. TSCM is one service among many, including infidelity, custody, and asset work, and it publishes no pricing or documented counter-surveillance cases.

11. AEGIS Security & Investigations

AEGIS Security & Investigations is a Culver City company established in 2007 and licensed by the California Bureau of Security and Investigative Services. It offers bug sweeps and wiretap detection for phones, computers, and physical spaces, and its Westside location makes it convenient for nearby clients.

AEGIS is mainly a security guard, training, and investigations provider, and its TSCM service is a small part of the business. Its public reviews mostly describe guard services, and it publishes no TSCM credentials, pricing, or case history.
