Security information and event management (SIEM) has come a long way since its inception over 20 years ago. Adoption was originally driven by The Payment Card Industry Data Security Standard (PCI DSS) but has since enjoyed widespread use due to its joined-up approach to identifying and combatting security threats.
Just monitoring one system in isolation isn’t suitable for modern-day security. According to the Global Incident Response Report by Palo Alto Networks, 87% of intrusions involve activity across multiple attack surfaces, including endpoints, networks, cloud, SaaS and identity.
So, it’s no surprise that SIEM has caught the eye of legislators, with the NIS2 directive (which covers many companies in the EU, and indirectly their supply chains) giving guidance that specifically recommends SIEM to aid compliance.
Here are five ways Kaseya SIEM helps organisations with NIS2 compliance.
1. SIEM helps identify security incidents faster
One of NIS2’s central requirements is the ability to detect, monitor and respond to cybersecurity incidents effectively. This is all about bringing together the data from across your organisation to detect potential threats and respond to them.
Guidance states that the ability to correlate information between systems is important for compliance. It also suggests SIEM as an evidence point for the monitoring and logging portion of incident handling.
Without this orchestration ability, you are looking at individual signals in isolation. SIEM is what brings them together to provide a unified picture of threats to your organisation.
2. SIEM provides the context needed for incident response
Detecting an incident is only the first step.
Organisations must also determine the severity of the threat, understand its potential impact and decide how to respond.
Is it a small security issue that can be fixed quickly and without further intervention? Or is the incident severe enough to trigger other parts of your security planning?
You can’t decide it in the moment. That pathway must be laid out clearly in advance. NIS2 guidance suggests ensuring you have clear criteria on what can be classed as an incident, how the severity is categorised and how you then handle it as a result.
But the SIEM data — and understanding the severity of the incident — is what provides that foundation of information that allows you to trigger the appropriate response.
3. Automation accelerates response times
Responding to an incident quickly could be the difference between nipping an issue in the bud versus that issue grinding your business to a halt. According to the CrowdStrike Global Threat Report 2025, it takes just 48 minutes on average for attackers to move laterally from initial compromise.
As part of incident response, NIS2 guidance suggests the use of automated solutions. Automation across cloud, email and endpoint can trigger an immediate response before an engineer even receives the notification.
Kaseya SIEM’s automated response rules stop threats without manual intervention. In fact, you can use automated response rules out of the box, or fine tune and create your own.
4. Tailored security helps you focus your efforts
Acknowledging the sheer wealth of data that could overwhelm a team, NIS2 guidance suggests utilising automation to triage incoming alerts and prioritise them based on severity.
NIS2 recognizes the importance of focusing resources on genuine risks and minimizing false positives wherever possible.
Kaseya SIEM allows you to define your own custom indicators of compromise and adjust alert severity. When combined with automated response, it allows you to tailor responses to fit your environment and ensure that your teams respond to what matters most.
5. Logs give the evidence you need after an incident
There is no set way an investigation may unfold, or indeed what may trigger one. But, if auditors do carry out an investigation after a security breach, having the right data on hand is vital.
Auditors will likely want to see how you handled the incident, the data used to inform your resolution and the steps you took. They may also want to see what data you were collecting and how you were interpreting and acting upon that data before the event.
With a 400-day log retention, Kaseya SIEM has that covered. And when you consider it takes an average of 241 days to identify and contain a breach, that length of log retention becomes even more important.
There’s SIEM — and then there’s Kaseya SIEM
Kaseya has taken SIEM and adapted it for modern threats. While SIEM has always been a powerful tool for aggregating data, Kaseya SIEM combines AI automation along with a high level of customisation so you can tailor and speed up your response to an incident.
The cost of not having a SIEM solution could also have wider ramifications. Many cyber insurers now require SIEM or SOC coverage as a condition of policy renewal. Kaseya SIEM offers both.
In addition to the automated responses and tailored alerting, Kaseya SIEM is also backed by a 24/7 SOC that scans for issues at all times.
NIS2 calls for the right tools with the right people and the right training — and by combining SIEM with SOC, Kaseya SIEM helps organisations tackle both parts of the requirement.
