A poorly chosen security company might result in you buying a bunch of software and services you don’t really need just because you stumbled upon a good cybersecurity salesperson. I recently worked with a company which was convinced they need a ‘firewall penetration test’ – a completely fraudulent service, because hackers rarely attack firewalls and if they do, they do so through attacking employees, not devices. And the firewall penetration test they purchased was done before the company had time to prepare. This is like attacking a village without time to build a fortress – what’s the point? It was defenseless to begin with!

Known mostly for its firewall products, it started offering vCISO services and incident response among its fleet of security appliances. If you are a bigger company, definitely worth checking them out. 

• Provides tools to prevent network threats.
• Brings a unified view for managing security across all systems.

Microsoft

An unexpected entry on the list, isn’t it? But if you think about it… Microsoft has more than a billion devices running its operating systems and receives security telemetry data from all of them. If an attack happens on one devices and their engineers process it, all these billion devices receive protection from similar attacks. Microsoft has one of the, if not the biggest security team of engineers out there. Thanks to that, its Defender family of products for endpoints, cloud and servers are unbeatable (in our opinion). 

• Focuses on antivirus, cloud, and endpoint security.
• Uses strong malware detection methods.
• Offers straightforward protection for individual devices.
• Works well for small to medium-sized businesses.
• Offers security services executed by architects and engineers for larger enterprises.

  • If you require basic antivirus and endpoint protection, they offer proven options.

You need a security engineer who’s been in the trenches. When choosing among computer security companies, look for pros with certifications like CISSP, CISA, or OSCP. They should have at least three years of hands-on experience in your industry. This background proves they understand your unique challenges and assets.

Their expertise leads to clear, actionable insights. An auditor who knows HIPAA inside out, for example, will carefully review your controls around electronically protected health information (ePHI). This practical know-how saves you time and money by quickly spotting real vulnerabilities.
