In today’s fast-evolving industrial landscape, safeguarding operational technology (OT) environments against cyber threats such as ransomware attacks and supply chain vulnerabilities has never been more critical. Traditional “blinking box” security solutions that rely solely on isolated devices like firewalls and antivirus software are no longer sufficient to defend against sophisticated and complex attacks. At Au2mate, we recommend a comprehensive, layered security strategy that combines multiple layers of safeguards to effectively protect your production environment, ensure OT security, and achieve NIS2 compliance.

Understanding the limitations of “Blinking Box” security

Limited scope: Single-point solutions often target specific threats, leaving other vulnerabilities, such as asset discovery and vulnerability management, exposed.
Reactive approach: Many systems rely on detecting known threats, making them less effective against new or sophisticated attacks like ransomware.
Operational blind spots: A lack of integration between security devices can create visibility gaps, especially in complex IT/OT convergence environments.

The benefits of layered security

Layered security addresses protection across multiple dimensions:

Physical security: Restricting access to critical infrastructure.
Network security: Deploying robust firewalls, Intrusion Prevention Systems (IPS), and network segmentation to defend against threats.
Endpoint protection: Implementing advanced threat detection and ransomware protection on devices.
Data security: Encrypting sensitive information both in transit and at rest.
Operational processes: Enforcing strict patch management, incident response plans, and regular audits.
User awareness: Educating staff on cybersecurity best practices to minimise human error.

From cost to investment: ROI in OT security

Investing in a layered OT security strategy is not only about defence but also about optimising operations and reducing downtime. By implementing network segmentation, continuous vulnerability management, and effective incident response, you can minimise losses from production stoppages and protect critical assets. Strong security practices also ensure NIS2 compliance, enhancing your company’s credibility and competitiveness. In essence, you’re not just protecting your OT systems; you’re investing in a more robust business with measurable ROI.

Typical vulnerabilities in OT environments

SCADA and PLC devices: Often run outdated firmware and lack regular security updates.
Lack of network segmentation: Makes it easier for attackers to move laterally within systems once they gain access.
IT/OT convergence: Combining traditional IT systems with OT devices creates new attack surfaces due to differing security levels.

Implementing layered security with Au2mate

At Au2mate, we specialise in delivering integrated OT/IT solutions, including tailored strategies for layered security in the manufacturing industry. Here’s how we can help:

Risk assessment: Comprehensive evaluations to identify vulnerabilities in your systems.
Network segmentation: Deploying VLANs, firewalls, and DMZs to isolate critical systems from external threats.
Endpoint security: Advanced solutions like Endpoint Detection and Response (EDR) and real-time monitoring tools to counter ransomware.
Proactive monitoring: AI-driven tools like DarkTrace enable real-time monitoring and ensure swift incident response, 24/7/365.
Compliance and reporting: Aligning security measures with industry standards like NIS2 and providing insights into network vulnerabilities using Tenable.
Training and simulation: Custom training programmes and simulated attacks using Cymulate to test the resilience of your security framework.

How our solutions make a difference

Network segmentation and security monitoring: We implement advanced solutions to ensure production systems are isolated and resilient to external threats.
AI-driven prevention:
Our systems, such as DarkTrace and Fortinet solutions, detect and respond proactively to real-time anomalies, minimising operational disruptions.
