Best Cybersecurity Software & Tools for 2021

Standalone security products are not enough to maintain the security posture of an entire organization. Between malware, phishing attacks, zero-day threats, advanced persistent threats, reconnaissance and brute force attacks, hackers are looking for any and every avenue into a network.

A number of solutions may be needed to protect against all of these threats. In this article, we’ll cover some of the most important tools to have in your security arsenal and some of the best vendors in each category.

We’ve narrowed this list down to four categories of products that are essential to modern cybersecurity: Endpoint detection and response (EDR), next-generation firewalls (NGFW), cloud access security brokers (CASB) and security information and event management (SIEM). And if you’re here looking for antivirus software, see our list of the best antivirus software for 2021.

Benefits of cybersecurity tools

Each type of product on this list offers multiple benefits as part of comprehensive cybersecurity defenses.

EDR benefits

Entry points are always at risk. EDR tools allow teams to continuously monitor endpoints for malware and other malicious attacks. Many of these solutions can also automatically respond to some threats and offer steps for remediation.

Many EDR tools are quickly converging with EPP. These tools offer more protection against advanced threats compared to traditional antivirus solutions, with the added benefit of centralized management. A tool that combines both EDR and EPP capabilities makes for a powerful combination that not only detects threats but stops them dead in their tracks.

NGFW benefits

NGFWs are the third generation of firewalls. This new era introduced multiple new features alongside traditional firewall capabilities. Some of the most beneficial include:

  • Intrusion prevention systems (IPS): This allows NGFWs to inspect, alert and actively remove malware and intruders.
  • Deep packet inspection (DPI): DPI offers targeted inspection and can locate, categorize, block or reroute packets that contain problematic code or data payloads.
  • Layer 7 application control: NGFWs can protect data in layer 7 of the OSI model, which presents data in a form that user-facing applications can use. This is commonly where distributed denial-of-service (DDoS) attacks take place, making it a critical layer to protect.

CASB benefits

CASB products are cloud-based or on-premises software that enforce security policies, regulatory compliance and governance requirements when accessing cloud services. These tools are able to manage single sign-on, log data, authentication and authorization, device profiling and encryption and tokenization.

CASB solutions can also block access to cloud services if they detect attempts to access resources from unauthorized users or applications. They also alert teams of malware and other possible attacks when they are detected.

SIEM benefits

SIEM products serve two primary purposes. The first is to collect, store, analyze, investigate and report on log and other data. The second is to alert security staff to the most important threats.

Insights pulled from this analysis help with the early detection of attacks, facilitate improved incident response and assist in maintaining regulatory compliance. SIEM systems also typically incorporate threat intelligence feeds that offer data on correlated events to help identify attacks.

Building comprehensive security

Many vendors offer comprehensive security suites that offer all the products you will need under one umbrella, sometimes packaged as XDR platforms. However, it is possible to pick and choose products to create a custom security suite. There are pros and cons to taking this approach.

Pros

Customizing your cyber defenses can be a good way to save money and avoid vendor lock-in. This allows you to choose some products that are on the cheaper side if they can fulfill your needs, or possibly bypass them completely. Or you may want to piece together “best of breed” solutions rather than going with a suite of solutions from a single vendor. There may be certain standalone products that are more tailored to your specific industry or use case to better serve your needs.

Cons

Researching all of the different standalone products and whether or not they are able to integrate well and be deployed on the same system can consume substantial time and effort on your part. And the more products you add from different vendors, the more complex it becomes to manage them all. Security platforms from a single vendor, on the other hand, can all be managed from a single, centralized dashboard.

How to choose a cybersecurity product

There are a few key factors you should consider when choosing the right security tools for your organization.

Types of threats

You should determine whether there are specific threats you’re most concerned about. For example, are you particularly wary of phishing, malware or advanced persistent threats (APT)? If so, look for a suite that specializes in these areas.

How much can you manage?

You should also determine how much you can realistically manage internally. Some security products are built to be intuitive or to provide substantial automation to take much of the management load off of security teams so they can focus on remediation efforts and other valuable aspects of the business. Other suites may require a more hands-on approach.

If you overestimate how much you can handle in-house, not only could this lead to gaps in your security but also other aspects of your business falling to the wayside. Choosing to customize your own security defenses is a good indication that you will require more internal management.

Integration

Ensure that any tools you’re researching will integrate well with your existing security infrastructure. Do you already have some security solutions in place? Then make sure they can operate harmoniously with a new security suite or other standalone products.

Scalability

If you foresee substantial organizational growth in the near future, ensure that your security solutions can scale in tandem. This often depends on how the pricing plans are set up. Some vendors may price their tools according to a per-device basis. In these cases, make sure you can also afford the higher-priced plans to accommodate your growth. And some security solutions can’t scale to the same capacity as others so buy with your future growth in mind.
