Top Cybersecurity Companies
In-depth Cybersecurity Company Profiles

Palo Alto Networks

Headquarters: Santa Clara, California

Founded: 2005

Annual Revenue: $4.2 billion

Cybersecurity product categories: Next-generation firewall, UEBA, cloud security, endpoint protection, threat detection and prevention, application framework

Appearances on eSecurity Planet‘s Top Vendors lists: 14

Topping our list is Palo Alto Networks (PANW), and for one very good reason: No vendor offers better security. The company’s results in rigorous independent tests have been stellar, whether in next-gen firewalls (NGFW), endpoint detection and response (EDR) or any other area. Its endpoint security tests have been consistently excellent, including in the new MITRE protection tests. And cybersecurity buyers have taken notice. Revenue at the 16-year-old Santa Clara firm is expected to grow 23% this year to top $4 billion. In all, we’ve named Palo Alto to 14 top product lists, and we expect that number to grow in the coming months. The company’s even entering the home and small biz market with the cool (but pricey) new Okyo WiFi 6, which made our list of the best Wi-Fi 6 routers. In addition to NGFW and EDR, these are the other enterprise security areas where Palo Alto ranks among the best:

Cloud security

Network security
Zero trust
Threat intelligence
Cloud access security broker (CASB)
User and entity behavior analytics (UEBA)
Intrusion detection and prevention systems (IDPS)
Extended detection and response (XDR)
Container and Kubernetes security
Cybersecurity products
IoT security


Headquarters: Sunnyvale, California

Founded: 2000

Annual Revenue: $2.6 billion

Cybersecurity product categories: Network firewalls, anti-virus, intrusion prevention, Network access control (NAC), web application firewalls and endpoint security.

Appearances on eSecurity Planet‘s Top Vendors lists: 13

With $2.6 billion in revenue and growing at a healthy 17%, Fortinet is expected to hit $3 billion in sales this year. The network security vendor is another that doesn’t shy away from rigorous testing, and that’s landed the company on 13 of our top cybersecurity software lists. Fortinet has been steadily building a reputation as one of the top security companies around. Customer satisfaction ratings are high and analysts have lauded the company too. Gartner gave it top place in unified threat management (UTM), and it was named a Leader in next-gen firewalls (NGFW). And the company continues to evolve and look to the future: it ranked well in the Gartner Magic Quadrant for WAN Edge Infrastructure, and has earned another year near the top of our list.

Headquarters: San Jose, California

Founded: 1984

Annual Revenue: $49.7 billion

Cybersecurity product categories: Next-generation firewalls, next-generation intrusion prevention, CASB, web gateway, NAC, advanced malware protection, email security, endpoint security, security management, VPN, security services

Appearances on eSecurity Planet‘s Top Vendors lists: 11

Cisco (CSCO) is a perennial favorite on this list. The networking pioneer has used its market dominance to move into adjacent markets, among them network security. With $3.2 billion in revenue and double-digit growth, security is one of Cisco’s strongest markets. Customers are often Cisco shops gravitating toward its firewall, endpoint and other products, but when you have nearly $50 billion in annual sales, your existing customers are a pretty big market, and Cisco has had its wins elsewhere too. Cisco has made 11 of our top security product lists: identity and access management (IAM), web gateways, NGFW, IDPS, CASB, NAC, IoT, cybersecurity software, XDR, network security and zero trust, with the company’s early leadership in the emerging and important zero trust market its most impressive recent accomplishment.



Headquarters: Sunnyvale, California

Founded: 2011

Annual Revenue: $1.4 billion

Cybersecurity product categories: EDR and XDR

Appearances on eSecurity Planet‘s Top Vendors lists: 4

While CrowdStrike (CRWD) made four of our lists – EDR, XDR, MDR and cybersecurity – coming out on top of the very competitive EDR market is no small accomplishment, and the company’s XDR platform leaves it well positioned for the future too. Apparently IT security buyers agree: Analysts expect stunning 56% revenue growth this fiscal year to rocket past the $1 billion sales mark. The 10-year-old Sunnyvale company could further gain after successfully fending off a SolarWinds-related attack, a distinction shared with Palo Alto Networks.



Headquarters: Armonk, New York

Founded: 1911

Annual Revenue: $74.3 billion

Cybersecurity product categories: Security analytics, services, patch management, encryption, SIEM, security orchestration, mobile security, fraud protection, network security, data protection, threat intelligence, application security, endpoint protection, identity and access management, authentication, database security, mainframe security

Appearances on eSecurity Planet‘s Top Vendors lists: 9

IBM’s deceptively large security business is spread across a number of business lines, like software and services, and the company doesn’t break out security revenues separately, but Big Blue is a powerhouse, making nine of our top security product lists: SIEM, IAM, encryption, database security, threat intelligence, single sign-on, patch management, managed security services, and cybersecurity products. Customer ratings are about average and the company’s speed in adding updates isn’t the best, but it remains popular with analyst firms like Gartner. IBM’s biggest strength might be its research depth, witness its impressive recent strides in homomorphic encryption.

Headquarters: Atlanta, Georgia

Founded: 2016

Annual Revenue: Privately held; GrowJo estimates $221 million

Cybersecurity product categories: privacy and compliance tools

Appearances on eSecurity Planet‘s Top Vendors lists: 3

Rocketing up the list this year is OneTrust. Startups crave unicorn status, a mark of success that means the private equity market has valued the company at $1 billion or more. OneTrust has done way better than that, raising $920 million in actual funding, for a $5.3 billion valuation. The privacy compliance technology company has ridden data privacy laws like GDPR and CCPA to become the fastest-growing company in America, according to Inc., number 4 on the Deloitte Technology Fast 500, and has earned spots on our risk management, third-party risk management and hot cybersecurity startups lists. A stunning rise for the 5-year-old Atlanta-based company.


Headquarters: San Francisco

Founded: 2009

Annual Revenue: $1.2 billion

Cybersecurity product categories: Zero trust, IAM, SSO, network security

Appearances on eSecurity Planet‘s Top Vendors lists: 4

Okta has a unique value proposition as a quick and easy way for organizations to get started implementing zero trust. With easy to use, deploy and manage products, it’s no wonder revenues are expected to soar 46% to $1.2 billion this year. In addition to zero trust, the 12-year-old San Francisco-based company also made our top IAM, network security and single sign-on lists.


Headquarters: San Jose, CA

Founded: 2007

Annual Revenue: $663 million

Cybersecurity product categories: Web gateways, zero trust, cloud security, edge security

Appearances on eSecurity Planet‘s Top Vendors lists: 2

Zscaler (ZS) is another one with outsized growth for an established company: analysts are expecting sales to surge 53% to $663 million this year. Zscaler, now in its 14th year, offers a broad cloud security platform that positions the San Jose-based company well for important emerging trends like zero trust, edge security and secure access service edge (SASE). Zscaler made our top web gateways list and received a mention for its zero trust efforts too.


Headquarters: Clearwater, Florida

Founded: 2010

Annual Revenue: $240 million

Cybersecurity product categories: Cybersecurity awareness training

Appearances on eSecurity Planet‘s Top Vendors lists: 1

KnowBe4 (KNBE) recently went public, so we can get a look at its finances for the first time. Not surprisingly, the numbers are impressive, with recurring annual revenue up 42% to $240 million in the company’s most recent earnings report. Founder and CEO Stu SJouwerman turned his vision for employee cybersecurity training into a dominant position in the all-important market. It’s a pretty secure market too, given that employees are the weakest link in the cybersecurity chain and ransomware and phishing remain top threats. The company boasts deep cybersecurity experience, leading to forays into other markets like compliance and email security.


Headquarters: Cambridge, UK

Founded: 2013

Annual Revenue: $278 million

Cybersecurity product categories: AI, threat detection, incident response, IDPS

Appearances on eSecurity Planet‘s Top Vendors lists: 2

UK-based Darktrace has made a name for itself as an innovator in AI-based security. We placed the company on our top IDPS list, but with broad detection and response capabilities, the 8-year-old venture between British intelligence agencies and Cambridge University mathematicians is not easy to categorize. A recent IPO gave investors a good look at the company’s finances, and 40% revenue growth suggests plenty of demand for this pioneering product.



Headquarters: Sunnyvale, California

Founded: 2002

Annual Revenue: $1.2 billion

Cybersecurity product categories: Advanced threat protection, email protection, encryption, data loss prevention, CASB, threat intelligence

Appearances on eSecurity Planet‘s Top Vendors lists: 5

Proofpoint’s (PFPT) revenues are expected to grow 15% to clear the $1 billion mark this year, as the Sunnyvale-based company rides a SECaaS product portfolio that has landed it on our top CASB, data loss prevention (DLP), zero trust, threat intelligence and email gateway lists. Proofpoint offers email protection, network sandboxing, security awareness training, cloud protection and more. It lags KnowBe4 in security awareness training, but its acquisition of Wombat is a statement that it intends to take that market seriously.


Headquarters: Boston, Mass.

Founded: 2000

Annual Revenue: $503 million

Cybersecurity product categories: SIEM, vulnerability management, application security, UEBA

Appearances on eSecurity Planet‘s Top Vendors lists: 7

Rapid7 (RPD) is a top SIEM, MDR, vulnerability management, vulnerability scanning, breach and attack simulation, application security and UEBA vendor, a broad portfolio that will lead the Boston-based cybersecurity company to 22% growth this year and more than $500 million in sales.


Check Point

Headquarters: Tel Aviv, Israel, and San Carlos, California

Founded: 1993

Annual Revenue: $2.14 billion

Cybersecurity product categories: Advanced threat prevention, next generation firewall, UTM, encryption, secure gateway appliances, endpoint protection, remote access, cloud security, mobile security, zero trust, incident response

Appearances on eSecurity Planet‘s Top Vendors lists: 12

Check Point’s 4% revenue growth may not turn heads, but it offers as complete a security portfolio in the industry, and with strong security and value too. Firewalls, gateways, UTM, EDR, threat intelligence, incident response, encryption and data loss prevention are just some of the areas the company ranks highly in. It is a Leader in Gartner MQs for UTM and NGFW. Customer satisfaction ratings are about average, but it comes up in eSecurity Planet top vendor lists regularly and has established a sound revenue base. Its EDR offerings are among the biggest bargains in the industry.

Trend Micro

Headquarters: Tokyo, Japan

Founded: 1988

Annual Revenue: $1.75 billion

Cybersecurity product categories: hybrid cloud security, intrusion prevention, advanced threat protection, encryption, endpoint security, email security, Web security, SaaS security, IoT security, threat intelligence

Appearances on eSecurity Planet‘s Top Vendors lists: 7

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.



Headquarters: San Jose, California

Founded: 1991

Annual Revenue: $27.25 billion

Cybersecurity product categories: Advanced threat protection, managed services, endpoint security, encryption, web gateway, email security, network security, cloud security, antivirus, identity theft protection, website security, mainframe security, IoT security, network monitoring

Appearances on eSecurity Planet‘s Top Vendors lists: 15

Getting acquired by chipmaker Broadcom hasn’t been a bad thing for the Symantec enterprise security business. With more than $27 billion in revenue and a 14% growth rate, there’s plenty of cash to bankroll promising investments. Symantec has made 15 of our top product lists, including endpoint security, CASB, WAF, web gateways, managed services, encryption, XDR, access management, DLP and zero trust. Symantec does well in Gartner MQs, tops in secure web gateways and a Leader in endpoint protection and managed security services. It even has decent product satisfaction scores. A longtime leader that’s not content to rest on its laurels.

Trellix tre

Headquarters: San Jose, California

Founded: 1987 (McAfee), 2004 (FireEye)

Annual Revenue: Privately held

Cybersecurity product categories: IDPS, web gateways, mobile security, enterprise cloud security, data protection, encryption, endpoint security, network security, XDR, security management, server security, security analytics, SIEM, web security, consulting, database security, ransomware removal.

Appearances on eSecurity Planet‘s Top Vendors lists: 15

Trellix, the name given to the merged entity of FireEye and McAfee Enterprise, appears on 16 of our top security products lists, but as all products have not been rebranded yet, we’ll continue to use the old names for now. And McAfee’s cloud business was spun off as a separate business, Skyhigh Security, so Trellix will focus on enterprise security and Skyhigh on edge and cloud security. Both companies are owned by private equity group Symphony Technology Group (STG) – which also owns RSA, our next entry on this list. McAfee has been a major player in security for a long time. We’ve named McAfee and FireEye products to our top security products lists 15 times, among them IDPS, SIEM, endpoint protection, secure web gateways, XDR, CASB, threat intelligence, encryption and DLP, but CASB is now a Skyhigh product and the two have a joint DLP offering. We’ll update the product rebrandings as they happen.



Headquarters: Bedford, Massachusetts

Founded: 1982

Annual Revenue: Undisclosed

Cybersecurity product categories: SIEM, GRC, threat intelligence, network traffic analysis and forensics, endpoint security, security orchestration, UEBA, malware detection, fraud prevention, identity and access management, third-party risk management.

Appearances on eSecurity Planet‘s Top Vendors lists: 7

Unlike Trellix, the merged McAfee-FireEye entity, RSA remains an independent company within STG’s security portfolio. RSA boasts strong products, a respected name and its eponymous conference among its considerable assets. We’ve given the company high marks in GRC, threat intelligence, encryption, SIEM, risk management and UEBA, among other areas. Customer ratings have been solid. The company has strong name recognition, but hasn’t stood out as much as that name would suggest. Further, weaknesses in RSA keys have called into question the security of its platform.



Headquarters: Abingdon, United Kingdom

Founded: 1985

Annual Revenue: Privately held; most recent data suggests $544 million in fiscal 2020

Cybersecurity product categories: Firewalls, unified threat management, secure web gateway, secure email gateway, security management, anti-phishing, endpoint protection, mobile security, encryption, server security, ransomware removal, consumer antivirus and Web filtering

Appearances on eSecurity Planet‘s Top Vendors lists: 10

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 10 of our top products lists: WAF, NGFW, UTM, EDR, encryption, XDR, MDR, ransomware removal, 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.



Headquarters: San Francisco, California

Founded: 2003

Annual Revenue: $2.53 billion

Cybersecurity product categories: Security analytics, SIEM, user behavior analytics (UEBA), ransomware prevention, security automation

Appearances on eSecurity Planet‘s Top Vendors lists: 2

Splunk is primarily an IT management vendor, but the company changed the security market with its cloud-based SIEM solution, and it’s still gaining traction, with double-digit growth expected the next couple of years. The Splunk platform can get pricey, but it’s also a low-upfront cost way for organizations to get into security analytics and SIEM. The company came up tops in Gartner’s MQ for SIEM but customer satisfaction ratings have slipped recently, in part because of pricing. Still, the company has taken a good chunk of business from long-term market incumbents and it looks like it will continue to do so for the next few years. We rate Splunk highly in both SIEM and security analytics. There have been recent reports that Cisco has tried to acquire Splunk, but no merger has yet materialized.


Headquarters: Redmond, Washington

Founded: 1975

Annual Revenue: $166.2 billion

Cybersecurity product categories: Identity and access management, UEBA, threat protection, information protection, security management, cloud security, DDoS protection, application gateway

Appearances on eSecurity Planet‘s Top Vendors lists: 4

Rounding out our list of the top security companies is Microsoft, which has quietly built up a large security portfolio. This includes Active Directory for identity and access management, Microsoft Defender, Azure cloud security services such as Security Center, Key Vault, Azure DDoS Protection, Azure Information Protection and Application Gateway for protecting Web applications. Its position in our rankings comes due to its general strong showing in all areas considered, and its overall analyst rating. Gartner placed Microsoft as tops in its Magic Quadrants (MQs) for endpoint protection and access management. What’s been really surprising is Defender’s very strong showing in the rigorous MITRE ATT&CK testing, with an unbroken string of stellar results. With the impressive security capabilities the software giant has developed, we can all hope the company uses some of that expertise to make Windows more secure.

Honorable Mentions
The cybersecurity industry is loaded with great companies. The following didn’t quite make our cut for the top cybersecurity companies, but that doesn’t mean they don’t have great products and services. Some continue to gain traction, while in other cases mergers and private equity takeovers – in the case of Mandiant, a pending merger with Google – have limited our visibility, but all these vendors have made our top product lists and will meet the needs of many users.

Cybersecurity is the top spending priority of CIOs, ahead of more strategic IT investments like AI and cloud, according to a recent Gartner survey. With the damage a breach can do to a company’s intellectual property and reputation – not to mention heavy fines under data privacy laws – companies have been pouring money into the $150 billion enterprise security market. But who are the market leaders? To find out, eSecurity Planet routinely conducts an analysis of the world’s largest and hottest cybersecurity vendors and ranks the top ones.

The biggest surprises in this list are the number of smaller vendors that are rapidly moving up, ahead of some more established names. Specialization can be a good thing in cybersecurity, witness CrowdStrike’s 56% growth rate. The vendors at the top of the list shouldn’t surprise longtime readers – Palo Alto Networks and Fortinet have continued to impress us – and a number of other vendors have withstood the test of time to stay on the list.

Vendors were evaluated based on their annual revenue, growth rate, range and quality of products, appearance on eSecurity Planet‘s top security product lists, user reviews, independent test results, analyst reports and venture capital funding, among other factors.
