As the demand for robust security defense grows by the day, the market for cybersecurity technology has exploded, as well as the number of available solutions.

To help you navigate this growing marketplace, we provide our recommendations for the world’s leading cybersecurity technology providers, based on user reviews, product features and benefits, analyst reports, independent security tests, and use cases. Between high-profile ransomware attacks and mergers, it is a time of high stakes and great change for the industry.

The Best Cybersecurity Companies


Fortinet has been steadily building a reputation as one of the top security companies around. Its revenues are increasing at a fast clip, it comes up repeatedly in eSecurity Planet top vendor lists, has high customer satisfaction ratings and does well in analyst ratings. Gartner gave it top place in unified threat management (UTM), and it was named a Leader in next-gen firewalls (NGFW).


Cisco’s roots are in networking but by necessity it has expanded into security and storage. Over the years, it has built up a wide range of security products, including firewalls, intrusion prevention systems (IPS), UTM, malware protection and cloud protection.


Microsoft has quietly built up a large security portfolio. This includes Active Directory for identity and access management, Windows Defender, Azure cloud security services such as Security Center, Key Vault, Azure DDoS Protection, Azure Information Protection and Application Gateway for protecting Web applications.

Palo Alto Networks

Palo Alto may not have the revenue totals of some of the big boys, but like Fortinet, it is very much on the rise. It offers firewalls, endpoint protection, cloud access and more. It boasts 50,000 customers, including more than 85 of the Fortune 100.


McAfee has been a major player in security for a long time. It doesn’t seem to dominate any particular slice of the market, but it offers a lot of products that do consistently well in diverse areas. This includes antivirus, identity protection, SIEM (where Gartner names it a Leader), endpoint protection (graded a Visionary by Gartner) and secure web gateways (Gartner Challenger).

Trend Micro

Trend Micro is another big name with modest growth and a dependable revenue base, with a broad array of security solutions that protect more than half a million organizations and a huge number of endpoints. The one area where it excels is in endpoint protection, where Gartner has included it as a Leader for 15 years, and impressive independent tests back that up. Customer satisfaction ratings appear to be on the rise and a bit above average even. IDPS, endpoint security, encryption, XDR, cloud security, and DLP are areas we’ve rated the company’s products highly in. Forrester just scored it highest in cloud workload security. With its AWS relationship and the release of a security services platform for organizations building applications in the cloud, Trend Micro is gradually making its way up the standings.


Sophos is one of the oldest security vendors on this list, from the 1980s era that also saw the founding of RSA, McAfee, Symantec and Trend Micro. It offers strong security in a number of areas, often at value pricing. That combination has landed Sophos on nine of our top products lists: WAF, NGFW, UTM, EDR, encryption, XDR, MDR, and even antivirus. Unlike Symantec and McAfee, which have separated their consumer and enterprise businesses, Sophos and Trend Micro have retained control of their consumer products, and Sophos offers a very good one that even uses some of its enterprise EDR artificial intelligence (AI). Other areas of strength include firewalls and network and cloud security, giving the company a good base for the emerging XDR market. It made the Leaders quadrant of Gartner’s MQs for endpoint protection and UTM. Customer satisfaction has improved recently and is now even a little above average in some areas. Its acquisition by Thoma Bravo makes financial visibility murkier, an unfortunate trend in security in general with the number of private takeovers that have happened.
