The Top Industrial Control Systems (ICS) Security Companies
According to Check Point’s Manufacturing Security Report, the manufacturing industry accounts for over 20% of all ransomware cases. Combined with other common threat vectors, this sector is consistently a highly valued target for attackers. Manufacturing enterprises need to seek out quality industrial control systems (ICS) security solutions to offer comprehensive protection against top threats.
We’ll explore the importance of ICS security and touch on the 10 leading security providers to consider when deciding on a reliable solution.
Key Takeaways
- Manufacturing is a top target for cyberattacks, being the #1 most targeted industry for ransomware attacks.
- The average ransomware attack in manufacturing costs $2.4 million, with an average breach totaling over $4.4 million.
- ICS security protects industrial systems from cyber threats that may disrupt their operations.
- A reliable ICS security provider should offer deep visibility, full segmentation to prevent horizontal movement, and threat detection.
- Check Point is the market leader for ICS security, offering virtual patching, granular industrial protection control, and AI-driven intelligence.
The Importance of ICS Security
Manufacturing organizations faced 1,585 cyberattacks per week on average in 2025. That’s a 30% year-over-year increase from 2024, which takes on even more weight considering attacks already increased by 90% in 2024 alone. The past few years have demonstrated that the manufacturing industry is a central target, and one that’s becoming increasingly more valuable for malicious groups.
ICS security is vital because this sector is continuously under attack from a range of malicious groups. Any small cybersecurity event or breach can create a major disruption to a manufacturing company, a piece of information that attacking groups leverage in ransomware and other attack cases.
By enlisting a strong ICS security solution, businesses are able to prevent common threats, respond to emerging vectors, and fortify their perimeters to block disruptions caused by cyber events.
Key Considerations When Selecting an ICS Security Provider
With so many ICS security providers to choose from, it can be a challenge to narrow down the right option for your business.
Here are three main considerations you should prioritize when selecting an effective ICS partner:
- Visibility: Providers should conduct automatic asset discovery to help provide an inventory of all your assets, legacy devices, and managed systems. Without complete visibility over your attack surface, a solution is unable to enforce effective security controls.
- Threat Detection: Your provider should compile information from active threat networks to understand how to prepare for emerging threats. Advanced solutions need to offer behavioral analysis and AI-driven insights to help identify zero-day threats and even sophisticated attack techniques before they impact operations.
- Compatibility: ICS security solutions need to fully support the industrial protocols used within your environment. They should be able to inspect and control ICS-specific communications without disrupting critical processes or causing downtime.
