Top 14 Cybersecurity Companies to Know

Firms in the cybersecurity sector are actively working to counteract digital threats, evaluate potential risks in the industry, and enhance knowledge and understanding about cybersecurity.

The financial impact of cybercrime is projected to reach a staggering $8 trillion worldwide in 2024, and it could escalate to an estimated $10.5 trillion by 2025.

This alarming trend is driving cybersecurity firms to take on a more proactive role in safeguarding a variety of entities.

Given their role as large-scale data gatherers and repositories, businesses are particularly vulnerable to cyber attacks.

This sentiment is echoed by IBM’s president and CEO, Ginni Rometty, who declared, “Cybercrime is the single biggest threat to every corporation globally.” The need for advanced cybersecurity measures is more pressing than ever, and firms are poised to implement cutting-edge cybersecurity solutions. Cybersecurity firms listed below are experts in anticipating, alleviating, and neutralizing cyber threats, allowing their clients and their clients’ customers to concentrate more on proactive measures rather than reactive defenses.

Network Security Companies

Palo Alto Networks

Palo Alto Networks, a company renowned for its extensive security solutions, is headquartered in Santa Clara, California. Since its inception in 2005, the company has grown significantly, boasting an annual revenue of $8.18 billion. It has made its mark on eSecurity Planet’s Top Vendors lists, appearing 19 times.

Palo Alto Networks (PANW) has consistently achieved high scores in independent security tests, including next-gen firewalls (NGFW), endpoint detection and response (EDR), and more.

The company’s comprehensive cybersecurity solutions are well-known, and it has also demonstrated its prowess in security services, securing a top-four position in the inaugural MITRE managed security tests. Its consistent excellence in security product tests, including the latest MITRE endpoint security tests and CyberRatings firewall tests, has not gone unnoticed by cybersecurity buyers. Industry analysts forecast that the Santa Clara-based company, now in its 18th year, will see its annual revenue grow at a rate of 27% over the next five years.

Palo Alto has been named to 19 top product lists and is expected to continue this trend in the future. Last year, the company won three categories in our cybersecurity product awards. Palo Alto continues to innovate, making significant announcements in areas such as automated threat response, DevSecOps, vulnerability and configuration management, and other areas of cyber resilience that are often overlooked in the detection-focused cybersecurity market.

While Palo Alto is primarily known for its robust security features, it has also made impressive strides in improving ease of use, pricing, and perceived value, indicating a concerted effort to expand its customer base. One setback was the discontinuation of Okyo, Palo Alto’s promising venture into home office security, although competitor Fortinet maintains its Wi-Fi security partnership with Linksys.

In addition to NGFW, EDR, and DevSecOps, Palo Alto excels in several other enterprise security areas, including:


Fortinet, a leading company in network security, is based in Sunnyvale, California. It was established in 2000 and has an annual revenue of $6.37 billion. The company has been featured 18 times on eSecurity Planet’s Top Vendors lists.

Last year, Fortinet secured the second position and is expected to maintain its rank this year as well. The company is predicted to grow at a rate of 17.9% annually over the next five years.

Fortinet is not one to back down from intensive testing, which has earned it a spot on 18 of our top cybersecurity software and hardware lists. The company excels in its primary area of network security, but it also demonstrates robust capabilities in other crucial security areas like SIEM and EDR.

Leveraging its networking expertise, Fortinet has successfully established itself as a leader in related markets such as SD-WAN. The company receives high customer satisfaction ratings in critical areas like product capabilities, value, ease of use, and support, which has helped it penetrate the small business market.

Industry analysts have praised Fortinet, placing it alongside Palo Alto and others in frequent appearances in Gartner Magic Quadrants and Forrester Wave reports. Fortinet has been recognized in the following eSecurity Planet top product lists:


Cisco, a leading company in distributed network security, is headquartered in San Jose, California. Since its inception in 1984, it has grown to generate an annual revenue of $54.53 billion. Cisco has been recognized 14 times on eSecurity Planet’s Top Vendors lists.

As a long-standing leader in the networking industry, Cisco has leveraged its strong market position to branch out into network security. Its security division, valued at $4 billion, is expanding at a robust 9% rate, outpacing the overall growth of the company.

Cisco’s customer base often consists of businesses that already use its networking products. These customers tend to adopt Cisco’s firewall, endpoint, and other security solutions. With annual sales exceeding $50 billion, Cisco’s existing clientele represents a substantial market. Moreover, Cisco has also achieved success in attracting new customers.

Cisco’s offerings have been featured 14 times on our top security product lists, including identity and access management (IAM), web gateways, network detection and response (NDR), SASE, SD-WAN, NGFW, IDPS, CASB, NAC, IoT, cybersecurity software, XDR, network security, and zero trust.

Its robust standing in the fiercely competitive EDR market and the burgeoning XDR market underscores its potential for future growth. The company’s revenue is projected to increase from $3 billion to $3.9 billion in the coming year, with an impressive anticipated annual growth rate of 40.4% over the next five years. This indicates a high level of consumer interest in CrowdStrike’s offerings.

The company, now in its 12th year, has demonstrated its capabilities by successfully defending against an attack related to SolarWinds, a feat also accomplished by Palo Alto Networks. Its top-ranking performance in the MITRE MSSP evaluations indicates that it is well-equipped to thrive in the rapidly expanding MDR market.


Zscaler, a company based in San Jose, CA, is recognized for its excellence in cloud security. Established in 2007, the company has an impressive annual revenue of $2.07 billion.

It has been featured six times on eSecurity Planet’s Top Vendors lists. This year, Zscaler (ZS) has climbed a few ranks on our list. The company is expected to generate $1.53 billion in revenue this year and has a promising long-term growth projection of 47.8%.

Thanks to its comprehensive cloud security platform, Zscaler is well-equipped to handle emerging trends such as zero trust, edge security, and secure access service edge (SASE). The company has made its mark on our SASE, zero trust, web gateway, deception tools, cloud security, and SD-WAN lists.


IBM, a company with a long history dating back to 1911, is headquartered in Armonk, New York. Despite not being the growth powerhouse it once was, it still commands respect in various IT markets, including security, thanks to its strong research and development capabilities.

The company, also known as Big Blue, has made its mark in 11 key security product areas, including UEM, container security, SOAR, SIEM, encryption, database security, threat intelligence, single sign-on, patch management, managed security services, and cybersecurity products.

Despite an annual revenue of $60.69 billion, IBM’s presence is still felt on eSecurity Planet’s Top Vendors lists, with 11 appearances to its name.

Trend Micro

Trend Micro, a Tokyo-based company established in 1988, is a top choice for small businesses. With an annual revenue of $1.77 billion and a presence on eSecurity Planet’s Top Vendors lists nine times, it has a solid reputation in the industry.

Recently, Trend Micro has shown impressive independent test results and has been developing a portfolio that is particularly attractive to small and medium-sized businesses (SMBs) and any security team that prioritizes user-friendly and robust security solutions.

The company, one of the pioneers in the antivirus market, not only excels in endpoint protection—being recognized as a Leader by Gartner for over 15 years—but also has a strong presence in Extended Detection and Response (XDR), application, cloud, and network security.

With high customer satisfaction scores for its value, ease of use, and capabilities, Trend Micro stands out as a strong contender for SMBs and others who prioritize these qualities. The company’s future prospects are also promising, with a projected long-term growth rate of 12%.


Okta, a company based in San Francisco and established in 2009, is recognized for its excellence in Access Management. Despite facing some hurdles, including security breaches, Okta maintains a strong presence in the crucial fields of Identity and Access Management (IAM) and Zero Trust.
