To compile our list, we started with innovation and market leadership, hence our focus on our rigorously researched top security product lists. Consistent performance, revenue, and growth were ranking factors, as were strong independent security test results in a market that’s starved for information. User reviews, product features, benefits and use cases, and analyst reports also played a role in our analysis.

Specialization can be a good thing in cybersecurity, witness the likes of CrowdStrike, Okta, and OneTrust high on our list. The vendors at the top of the list shouldn’t surprise longtime readers — Palo Alto Networks and Fortinet continue to impress us — and a number of other vendors have also withstood the test of time.

Frequently Asked Questions (FAQs)

The following questions are some of the most common from individuals researching security technologies and jobs.

What Are the Main Types of Cybersecurity?

While the security industry is broad and nuanced, there are a few widely recognized categories of security:

  • Network security: Protects the connections between networks, including data transfers to and from the internet, and hardware like routers and switches.
  • Endpoint security: Defends devices like laptops, phones, and servers.
  • Application security: Adds protection for software, data, and access at the individual application level.
  • Cloud security: Protects cloud environments and data from vulnerabilities and threat actors.

Also note that some security solutions cover multiple categories. Extended detection and response (XDR), for example, pulls alerts from endpoints, networks, and applications into a single console for centralized management.

How Do You Choose a Cybersecurity Company?

Choosing a cybersecurity vendor involves multiple factors, including company focus, integration issues, customer support needs, your team’s skill level, and your budget. Consider the following questions when choosing a cybersecurity vendor:

  1. What is the company’s overall focus? If you’re searching for a container security solution, consider a vendor that specializes in cloud and application security.
  2. How many of their solutions will you use? If you have software or hardware from another security vendor, do they integrate well? And look at support for other applications too.
  3. What are your customer support needs? Signs that a vendor has good technical service include 24/7 support in multiple channels and high praise for the support team in reviews.
  4. Can your business afford it? Some smaller businesses might not have the budget for vendors like Palo Alto and CrowdStrike, and that’s okay. There are plenty of providers that have security solutions designed for small companies.

Will Cybersecurity Jobs Become Obsolete?

If you’re a job seeker in the security industry or considering a career change, know that cybersecurity careers aren’t going anywhere. They might continue to change as the industry evolves, but demand for cybersecurity skills and training remains strong. Today’s IT climate requires knowledge of large security platforms, detection and response technologies, and even sometimes distributed systems.Job seekers will need to research the field and curate skills that will be most useful to potential employers. Organizations like EC-Council and CompTIA+ have certifications that provide a springboard for individuals wanting to start a security career. And continued education is critical for staying on top of threats — never stop learning.

What Are the Top Cybersecurity Companies to Work For?

The following companies are a sample of highly rated enterprises with strong security solutions. If you’re job searching or considering a career change, look at open roles with these tech organizations.

SentinelOne offers good benefits and receives a 4.6 out of 5 stars on Glassdoor. SentinelOne is also comparatively small in the security industry, with fewer than a thousand employees. And the company boasts some pretty stellar cybersecurity products too.

Netskope offers flexible spending accounts, a 401(k), and employee stock purchase plans to its personnel. It earns 4.5 stars from Glassdoor employee reviews. Netskope specializes in SASE, CASB, and SD-WAN technology.

Palo Alto Networks has employee benefits like stock purchase plans, development courses, and a 401(k). It earns 4.1 stars on Glassdoor. Palo Alto has some of the best and broadest security in the entire industry so there’s lots of opportunity to experience different facets of security.

Fortinet offers benefits like unlimited PTO, a health savings account, and a 401(k) to employees. It too has 4.1 stars on Glassdoor. Fortinet is known for its firewalls but excels elsewhere as well, including in SIEM and EDR.

And don’t forget big IT vendors with a security presence. Cisco (4.3 stars from Glassdoor) and Microsoft (4.3) are two standouts to consider.

And lastly, CyberArk offers an investment program, employee recognition program, and tuition reimbursement. The IAM leader receives 4.1 stars on Glassdoor.

Bottom Line: Top Cybersecurity Companies

The enterprise security market is a wide one, covering a range of technologies and systems that need to be protected. Some vendors offer a variety of products, while others specialize in just one or two.

To choose a potential provider for your business, consider your needs first before searching for the right fit. While all the vendors listed above offer strong solutions, it’s worth the effort to research and demo products until you find one well suited to your organization’s cybersecurity needs.
