Network segmentation with a next-generation firewall (NGFW) is a critical first step in securing an operational technology (OT) network. Industrial firewalls for OT networks typically demand a tough exterior while also containing specific, purpose- built controls and cybersecurity for unique industrial (non-IT) networks.

Production and personnel safety are critical in industrial control systems (ICS). Industrial networks include IT servers and unique, protocol-driven operational technology (OT) devices. OT security solutions must be customized to be effective in the vast industrial communication protocol environment.
The benefits of digital transformation (DX) have driven organizations to adopt new technologies that take time to transition into the scope of security operations. Industrial organizations with substantial operational technology (OT), such as industrial control systems (ICS) and supervisory control and data acquisition (SCADA) equipment, are no exception. OT environments face bigger DX challenges, however, because the technologies involved are often quite old.

Cybercriminals are becoming ever more sophisticated and capable of successfully bypassing existing protection. Every area of your business can be exposed to risk, disrupting business‐critical processes, damaging productivity and increasing operating costs.
It may not always be possible to halt a threat before it penetrates the security perimeter, but it’s absolutely within our power to prevent the attack from spreading and to limit or exclude the resultant potential damage. And, when it comes to complex or targeted attacks, speed of incident resolution is critical.
Counteracting today’s cyberthreats requires a 360‐degree view of the tactics and tools used by threat actors. Generating this intelligence and identifying the most effective countermeasures requires constant dedication and high levels of expertise.
Threat intelligence involves the collection of vast volumes of raw data about current or potential threats to an organization, which is then refined using a combination of machine‐learning algorithms and human expertise to produce actionable insights. Security operations centers (SOCs) can use such insights to increase their threat detection, investigation and hunting capabilities to prevent future cyberattacks.
Relevant threat intelligence feeds from trusted sources bring real value, while threat intelligence platforms can help to overcome issues in managing and integrating these feeds with existing security processes. However, customers have to carefully select these products to avoid the potential pitfalls.
While many organizations utilize cybersecurity solutions like endpoint protection platforms (EPP), around 10% of cyber threats – including new, unknown and evasive threats such as many types of ransomware – are capable of bypassing these defenses.
