Intrusion Detection Systems (IDS) can protect against today’s most dynamic and sophisticated threats, but the technology alone isn’t enough – it must be tailored to the business environment, closely monitored and rigorously updated.

Our Managed IDS service solves these challenges, expertly configuring appliances to better defend critical assets, maintain availability and ensure compliance.

How can a managed IDS service from Capula help to achieve compliance?

Interpreting the alerts that Intrusion Detection Systems (IDS) generate requires a high degree of security knowledge to help to prioritise and plan your actions.

Yet many organisations lack the security expertise required to ensure they get the most from the investment in these sorts of systems.

Our IDS managed monitoring services relieve this pressure by providing a team of Operational Technology (OT) Security professionals, able to analyse and triage alerts and providing actionable mitigation guidance to respond swiftly and effectively to them.

Our IDS managed monitoring services also enables you to achieve a number of ISA/IEC 62443-3-3 security requirements related to continuous monitoring and timely response to alerts.

Our Services

Our customers can benefit from a range of specialist and targeted monitoring solutions, designed to ensure you can select the level of service and support you need for your business.

Client Logo
Standard Monitoring

Our basic level of response, this solution delivers a notification service that keeps your informed of important events that require your team to take action. A periodic report of incidents and responses is provided monthly.

Client Logo
Advanced Monitoring

Intrusion Detection Systems require a certain amount of tuning to maintain a high level of performance due to inevitable changes in the underlying network and operations, and to keep pace with the latest rule sets.

Our advanced monitoring service offers everything our standard service offers with the inclusion of regular periodic cyber analysis, and scheduled reviews that maximise detection capabilities and reduce false positives – all helping to increase business efficiencies and performance.

Security Response Consultancy

In the event of a security incident or delivered on an ad-hoc basis, we can provide consultative advice to our customers’ challenges, diagnosing and investigating security incidents, performing maintenance or configuration, or delivering tuning tasks to Radiflow systems.

We can also provide consultative services on OT security s ubjects such as design assessments, mitigation recommendations and policy assessments.

Continuous risk assessments

Regular risk assessments are a key part of planning and implementing secure OT networks as described in ISA/IEC 62443-2-1.

Through deployment of the CIARA we can simulate attacks on the digital model of your OT network to produce an overall risk score based on industrial sector and geolocation, and on the security mitigations that you have deployed.

However, whilst CIARA produces compliance and risk reports on demand, any changes (or prospective changes) can impact the security landscape significantly. Performing further human assessments helps to provide additional insights into the network, ensuring that conclusions being drawn are relevant to your business context.

We typically perform this service at the start of an engagement with a new customer site, and then on a rolling 6 monthly interval.

Radiflow CIARA is the first-of-its-kind data-driven risk assessment & management platform for industrial organizations.

Serving as a stakeholder decision-support tool, CIARA empowers CISOs and owners of complex ICS environments to increase the effectiveness of their risk-mitigation measures throughout the entire system lifecycle, while optimizing cybersecurity expenditure.

CIARA employs a fully-automated, data-driven Breach & Attack Simulation (OT-BAS) engine, which calculates the success likelihood of different attacker techniques and effectiveness of risk-mitigation measures, using thousands of data points for network, asset, locale, industry, adversary capabilities and attack tactics.

The result is a comprehensive mitigation roadmap (fully ISA/IEC 62443-compliant), prioritized by each mitigation control’s contribution to overall risk reduction, thus maximizing cybersecurity ROI.
