What is cybersecurity?

Cyber security is a collection of methods to safeguard systems connected to the internet.

Computers, networks, software, and data can all be protected. Cyberattacks are used to gain illegal access, modify or obliterate data, or demand payment. Some frequent cyber-attacks include phishing, malware, social engineering, and ransomware.

Organizations and individuals can use cyber security to safeguard their systems and data against illegal access.

Organization names

Palo Alto Networks

Founded: 2005

Annual Revenue: $4.2 billion

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

Palo Alto Networks (PANW) is at the top of the list for one perfect reason: No provider provides superior security. Whether in next-generation firewalls (NGFW), endpoint detection and response (EDR), or any other, the company’s performance in meticulous independent tests has been outstanding.

 It has performed exceptionally well in endpoint security tests, including the brand-new MITRE protection tests. And buyers of cybersecurity have taken notice.

The 16-year-old Santa Clara company’s revenue is anticipated to increase by 23% this year, surpassing $4 billion. Palo Alto has been included in 14 top product lists, and we expect that number to rise soon.


Founded: 2000

Annual Revenue: $2.6 billion

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

Fortinet is anticipated to reach $3 billion in revenue this year with a current income of $2.6 billion and solid 17% growth. Another e-company that provides network security is another that doesn’t back down from rigorous testing.

As a result, it has earned a spot on 13 of our best lists of cybersecurity software. One of the leading security companies, Fortinet, has been rapidly gaining recognition. High levels of customer satisfaction are reported, and analysts have also praised the business. It was rated as the top unified threat by Gartner.


Founded: 1984

Annual Revenue: $49.7 billion

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

A constant favorite on this list is Cisco (CSCO). The industry leader in networking has expanded into related areas, including network security, by leveraging its market supremacy.

Security is one of Cisco’s most substantial areas, with $3.2 billion in revenue and double-digit growth. Clients frequently choose Cisco shops when looking for a firewall, endpoint, and other solutions, but your current customers represent a sizable market with your annual sales close to $50 billion.


Founded: 2011

Annual Revenue: $1.4 billion

product categories: EDR and XDR

Even while CrowdStrike (CRWD) appeared on four of our lists (EDR, XDR, MDR, and cybersecurity), winning the fiercely competitive EDR industry is no small feat, and the business is also well-positioned for the future thanks to its XDR platform.

Buyers of IT security appear to agree, as analysts predict a spectacular 56% revenue growth this fiscal year to surpass $1 billion in sales.


Founded: 1911

Annual Revenue: $74.3 billion

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, and mainframe security.

IBM is a powerhouse on nine of our top security product lists, including SIEM, IAM, encryption, database security, threat intelligence, single sign-on, patch management, and cybersecurity products.

The company’s deceptively large security business is spread across several business lines, including software and services, and it doesn’t break out security revenues separately.

Although the company’s average customer satisfaction ratings and update speed aren’t the best, analyst firms like Gartner continue using it.


Founded: 2016

Annual Revenue: Privately held; GrowJo estimates $221 million

product categories: privacy and compliance tools

OneTrust is surging up the list this year. Startups aspire to have unicorn status, a sign of achievement that indicates the private equity market has valued the business at least $1 billion. The privacy compliance technology company has benefited from data privacy regulations like GDPR and CCPA to become the fastest-growing business in America.

It is also ranked number 4 on the Deloitte Technology Fast 500 and has earned spots on our lists of top risk management, third-party risk management, and hot cybersecurity startups.


Founded: 2009

Annual Revenue: $1.2 billion

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

Okta has a unique value proposition as a quick and easy way for organizations to implement zero trust. It’s easy to use, deploy, and manage products.

In addition to zero trust, the company also made our top IAM, network security, and single sign-on lists.


Founded: 2007

Annual Revenue: $663 million

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

Another well-established firm with unusually high growth is Zscaler (ZS), which analysts anticipate will have a broad cloud security platform. It is well-positioned for significant new trends, including zero trust, edge security, and secure access service edge.

Zscaler is situated in San Jose (SASE). Zscaler made our list of the best web gateways and was recognized for its zero-trust work.


Founded: 2010

Annual Revenue: $240 million

product categories: Cybersecurity awareness training

Since KnowBe4 (KNBE) recently went public, we can now look at its financial situation first. The founder and CEO established a commanding presence in the crucial sector by implementing his concept for cybersecurity training for employees.

The industry is also relatively safe since people are the weakest link in the cybersecurity chain, and ransomware and phishing are significant concerns. Due to the company’s extensive experience in cybersecurity, it has entered sectors including compliance and email security.


Founded: 2013

Annual Revenue: $278 million

product categories: AI, threat detection, incident response, IDPs.

Darktrace, based in the UK, has established a reputation as a leader in AI-based security. We ranked the business at the top of our IDP list. Still, the eight-year-old collaboration between British intelligence services and mathematicians at Cambridge University is difficult to classify because of its broad detection and reaction capabilities.


Founded: 2002

Annual Revenue: $1.2 billion

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

The Sunnyvale-based business has a SECaaS product portfolio, placing it on our top CASB, data loss prevention (DLP), zero trust, threat intelligence, and email gateway lists. Proofpoint provides email protection, network sandboxing, security awareness training, cloud protection, and other services.


Founded: 2000

Annual Revenue: $503 million

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

Rapid7 (RPD), a leading provider of SIEM, MDR, vulnerability management, vulnerability scanning, breach and attack simulation, application security, and UEBA, will see 22% growth this year and more than a million in sales thanks to its diverse portfolio. Rapid7 is a cybersecurity company with headquarters in Boston.

Check Point

Founded: 1993

Annual Revenue: $2.14 billion

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

Although Check Point’s 4% revenue growth may not be noteworthy, the company offers the most comprehensive security portfolio in the sector and significant security and value.

The company excels in many areas, including encryption, data loss prevention, firewalls, gateways, UTM, EDR, threat intelligence, and incident response. In Gartner MQs for UTM and NGFW, it is a leader.

Trend Micro

Founded: 1988

Annual Revenue: $1.75 billion

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

Another well-known company, Trend Micro, has steady sales growth and an extensive portfolio of security products that shield more than 500,000 companies and a staggering number of endpoints.

Endpoint protection is the one area where it truly shines, and outstanding independent testing supports Gartner’s designation as a leader in this space for the past 15 years.

Customer satisfaction ratings seem to be rising and are even slightly above average. We have given the company’s solutions good marks in IDPs, endpoint security, encryption, XDR, cloud security, and DLP. Forrester has given it the highest rating in cloud workload security.

Trellixtrellix logo

Founded: 1987 (McAfee), 2004 (FireEye)

Annual Revenue: Privately held

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.

Trellix, the name given to the combined company of FireEye and McAfee Enterprise, is listed on 16 of our lists of the best security solutions; but, as all of the products have not yet undergone rebranding, we will continue to use the previous names for the time being.

Skyhigh Security, a new company spun out from McAfee’s cloud division, will focus on edge and cloud security, while Trellix will concentrate on corporate security.

The private equity firm Symphony Technology Group (STG), which controls RSA, the next company on our list, owns both businesses. McAfee has long been a significant figure in the security industry.
