Top 7 Cybersecurity Companies in Los Angeles (2026)
Last updated: November 3, 2026
Table of Contents
Consilien is the top cybersecurity company in Los Angeles for 2026, scoring 9.6/10 for a US-based 24/7 SOC, SIEM, pen testing, and a vCISO under one roof. Advanced Networks builds MDR into every IT plan, Be Structured leads on finance audit support, and Crimson IT carries the biggest review record. A six-factor Confidence Score ranked seven firms.
Quick Picks
- Best Overall: Consilien
- Security Built Into Every IT Plan: Advanced Networks
- FINRA and PCI Audit Support: Be Structured
- Biggest Review Record: Crimson IT
- Security-Led Managed IT: CyberDuo
Hiring one of the cybersecurity companies in Los Angeles usually starts after something goes wrong. A wire transfer lands in the wrong account, an insurer sends a 40-question renewal form, or a client asks for a SOC 2 report you don't have. By then you want a shortlist you can trust, not seven tabs of marketing copy.
This one was built from data anyone can check. Google ratings came from Google Maps and Clutch ratings from each firm's Clutch profile, both read on November 3, 2026. Every firm's services were checked on its own website the same day, and awards counted for more when the publisher's own list confirmed them. Consilien publishes the ranking. It scored first on the standard model below, with no weights moved.
Four firms from older versions of this page, or from Google's results for these searches, didn't make it. Two sell alarm systems and cameras, one lists only a Salt Lake City office, and one hasn't updated its website since 2021.
How These Cybersecurity Companies Were Ranked
Each firm got a Confidence Score out of 10, built from six factors and applied the same way to all seven. It's this publication's own number. Clutch and Google don't publish it.
A firm with no Clutch reviews keeps three quarters of the review score. An award only found in the firm's own press release counts for less than one on the publisher's page. Reviews get the biggest share because a firm can't write its own, and Clutch verifies each reviewer before a review goes up.
The Top 7 Cybersecurity Companies in Los Angeles
1. Consilien: Best Overall
Confidence Score: 9.6/10
Clutch 4.9 (6 reviews) | Google 4.9 (13 reviews) | Torrance | Founded 2001
At 3 a.m. a Consilien alert lands with a US-based SOC that's staffed all night, and the same company runs your network in the morning.
Key Strengths
- SIEM on the upper tier. It's software that piles the logs from every laptop, server, and Microsoft 365 account into one feed, so a weird overseas login and a new mail-forwarding rule two minutes later get read as one break-in instead of two unrelated blips.
- Pen test findings go to the same engineers who manage the network. Nobody has to forward a PDF to a different vendor and wait.
- There's a vCISO (think part-time security chief) on the account. Only three of the seven firms here offer one.
- #306 on the 2026 MSP 501, confirmed on the publisher's list, and 25 years in business.
Limitations
- Thirteen Google reviews and six on Clutch. That's a thin public record next to Advanced Networks or Crimson IT.
- If all you want is one pen test a year, a testing-only shop will quote less.
- NIST, CMMC, and SOC 2 work is billed under a separate Managed Compliance Program. Cleaner contracts, yes, but plan for two invoices.
Best For: Businesses that want IT, round-the-clock monitoring, and a named security lead accountable to them, particularly manufacturers and companies facing a CMMC or SOC 2 deadline.
Not Ideal For: Companies with an in-house SOC that only need outside testing once a year.
Services: 24/7 SOC monitoring, SIEM, endpoint security, incident response, vulnerability management, penetration testing, security awareness training, vCISO, managed and co-managed IT, plus a separate Managed Compliance Program
Industries: Manufacturing and distribution, professional services, entertainment and creative, engineering and architecture, real estate management
Why It Ranks #1: Consilien is one of only two firms here with a top security score, the only one of those two with a confirmed 2026 MSP 501 rank, and it has the longest track record of the seven. Its reviews hold it back more than anything else. Read how Consilien runs managed cybersecurity in Los Angeles.
2. Advanced Networks: Security Built Into Every IT Plan
Confidence Score: 9.0/10
Clutch 5.0 (44 reviews) | Google 5.0 (87 reviews) | Westwood | Founded 2004
Advanced Networks puts its Advanced Shield security platform in every managed IT plan, so there's no upsell conversation about whether you're covered.
What It Does Well
- The best review record on this list: 5.0 on both Clutch and Google across 131 reviews.
- MDR, incident response, ransomware recovery, pen testing, identity management, and a virtual CISO.
- Compliance pages for SOC 2, CMMC, PCI DSS, GLBA, the FTC Safeguards Rule, and NIST CSF, plus video client stories from LA Weekly, Eataly, and a few others.
Worth knowing: The "#36 MSP" figure on its homepage dates to 2024, and its 2026 MSP 501 placement couldn't be found on the publisher's list. It's built as a full MSP, so a company that only wants security still buys an IT plan.
Best For: Companies that want one flat monthly bill covering both IT and security.
Not Ideal For: Businesses with a solid internal IT team that just need a security layer on top.
Why It Ranks #2: On reviews alone it would win. It loses ground on awards, where nothing from the last two years could be confirmed.
3. Be Structured Technology Group: FINRA and PCI Audit Support
Confidence Score: 8.7/10
Clutch 4.9 (5 reviews) | Google 5.0 (65 reviews) | Downtown LA | Founded 2007
The homepage says IT support. The security menu reads more like an MSSP's.
Key Strengths
- SOC-as-a-Service, endpoint detection and response, privileged access management for the admin accounts attackers want most, and dark-web scanning for leaked passwords.
- Audit support for FINRA and PCI, with named case studies including Salem Partners and Hurwitz Creative.
- A California C-7 low-voltage license, so the same vendor can run cable and configure the firewall. Odd, and occasionally very handy.
The catch: No vCISO on the site, and the SOC is sold as a service rather than described as an in-house team, so ask who staffs it. Its 2026 MSP 501 rank of #282 comes from the firm's own announcement.
Best For: Wealth managers and financial firms preparing for a FINRA exam.
Not Ideal For: Companies that want a part-time security executive setting strategy.
Why It Ranks #3: Near-perfect Google reviews and the deepest finance-specific security work on the list.
4. AllSafe IT: Packaged Security for Smaller Teams
Confidence Score: 8.5/10
Clutch 4.9 (19 reviews) | Google 4.8 (39 reviews) | Pasadena | Founded 2005
AllSafe sells security as a bundle called SafeTotal, which is easier to budget for than a menu.
Where It Shines
- Threat detection, endpoint protection, a managed firewall, email security, and staff training in one package, with pen testing and IT audits available on top.
- Says it's SOC 2 certified.
- Steady reviews on both platforms, and offices in Pasadena, Hollywood, and Orange County.
The tradeoff: No SOC, incident response, or vCISO is named on its site. Its CRN MSP 500 placements for 2025 and 2026 come from its own announcements.
Best For: Nonprofits, hospitality, and retail businesses that want a packaged plan.
Not Ideal For: Companies that need incident response written into the contract.
Why It Ranks #4: Balanced numbers everywhere, without a standout security service.
5. Crimson IT: Biggest Review Record
Confidence Score: 8.1/10
Clutch: no reviews yet | Google 4.9 (98 reviews) | Downtown LA | Founded 2011
Key Strengths
- 98 Google reviews at 4.9, the most of any firm here.
- MDR, a 24/7 SOC, pen testing, incident response, and cloud security.
- #390 on the 2026 MSP 501, confirmed on the publisher's list, and named testimonials from groups like Project Angel Food and the Downtown Center BID.
Watch for: Its Clutch profile has no reviews, which costs it a quarter of the review score. No vCISO is listed, and its compliance pages don't mention CMMC or SOC 2.
Best For: Nonprofits, real estate groups, and multi-location organizations.
Not Ideal For: Defense suppliers who need CMMC guidance.
Why It Ranks #5: Strong security and real recognition. A few Clutch reviews would move it up.
6. CyberDuo: Security-Led Managed IT
Confidence Score: 7.5/10
Clutch 5.0 (39 reviews) | Google 5.0 (23 reviews) | Glendale | Founded 2016 per its California filing (Clutch lists 2008)
CyberDuo's homepage line is "Managed IT, run by a cybersecurity team," and for once the service page agrees with the slogan.
Strengths
- It runs its own SOC around the clock instead of reselling one, and adds pen testing, zero-trust access, and a vCISO.
- It went through a SOC 2 Type II audit itself. An outside firm watched its controls for months, which is the same test it'll be asking you to pass.
- A 5.0 average on both Clutch (39 reviews) and Google (23).
Limitations: No 2025 or 2026 awards turned up anywhere, and its founding year depends on who you ask. The California filing says 2016, so that's what got scored.
Best For: Private equity, legal, and finance firms that want security to lead the IT relationship, managed or co-managed.
Not Ideal For: A five-person office trying to keep IT under a few hundred dollars a month.
Why It Ranks #6: Quality isn't the problem. Age and the empty awards column are.
7. ClearFuze: IT First, Security Second
Confidence Score: 7.3/10
Clutch 5.0 (2 reviews) | Google 5.0 (52 reviews) | Brentwood | Founded 2002
ClearFuze's homepage has a small yellow plane flying over the downtown skyline, and founder Jason Gilbert happens to be a commercial pilot. The company itself is a managed IT shop out of San Vicente Blvd that does the security basics and doesn't oversell them.
Good At
- 24/7 monitoring, MFA, and staff training, run by engineers with the CISSP.
- A three-team setup per client: someone for the relationship, the help desk, and projects.
- A 5.0 average across 52 Google reviews, and more than two decades in business.
Gaps: There's no SOC, MDR, pen testing, or vCISO anywhere on the site, and the testimonials are signed with initials, so you can't call anyone.
Best For: An architecture or media firm whose real problem is laptops and Wi-Fi that keep breaking.
Not Ideal For: A company with an audit due this year.
Why It Ranks #7: People love working with ClearFuze. The security side just isn't where it puts its effort.
Also Scored, Just Outside the Seven
Three more firms went through the same scoring and landed below ClearFuze.
Resecurity (6.8) is a downtown threat-intelligence software company that tracks attacker groups and stolen data for big enterprises and government agencies. Serious security, but it isn't an IT partner for a typical business, and it has only ten Google reviews.
IT Accuracy (6.4), on Wilshire Blvd, does pen tests and network audits and has a 4.9 average across 58 Google reviews. Nothing on its site mentions a SOC or MDR, though, so ask who's watching at midnight.
Marvis Technology (5.8) has the biggest Google record of any firm scored, 99 reviews at 4.9. Its website doesn't list a street address or a team, and there's no Clutch profile, which is why it sits at the bottom.
How to Choose a Cybersecurity Company in Los Angeles
Start with the night shift. Five of the seven name a SOC or MDR service on their own sites (Consilien, Advanced Networks, Be Structured, Crimson IT, CyberDuo), and for the other two you'll have to get someone on the phone and ask what happens to an alert at 11 on a Saturday.
Then look at your calendar. A FINRA exam points toward Be Structured. CMMC or SOC 2 points toward Consilien or Advanced Networks, and CyberDuo has been through a SOC 2 Type II audit of its own, which tells you it knows what auditors ask for.
Headcount is a bad filter. A twelve-person architecture studio and a twelve-person wealth manager need very different things, and the wealth manager's regulator won't care how small it is.
Before signing, scroll to the newest Google reviews rather than trusting the average, ask which office your account will actually run out of, and call two clients in your line of work.
And if you already run a SOC of your own, you're not shopping for an MSP at all. You want a threat-intelligence vendor or a pen-test firm.
