Phishing attacks up 1265% - driven by Generative AI

Does Security Information and Event Management (SIEM) still have a role in modern SecOps?

It’s a valid question. In an age of AI-driven attacks, many cyber defenders find legacy SIEM tools are increasingly complex, cumbersome, and hard to manage – but that doesn’t mean SIEM tools lack purpose in a modern SOC.

After all, SIEM can provide valuable insight into threats to your IT infrastructure, using log and incident management, event correlation, alerts, and reports to give a real-time overview across servers, devices, and applications.

So, SIEM isn’t destined for the scrapheap just yet.

However, what Security Operations teams do need is more speed, time, and resources – and an AI-powered SIEM can give those back to you.

Overcoming the limitations of a legacy SIEM: two approaches

With a growing volume of attacks, your SIEM must enable you to cut down your reaction speed to the irreducible minimum.

Following the introduction of generative AI (in November 2022), there has been a 1265% increase on phishing attempts. The number of cloud intrusions also increased by 75% in 2023.

It’s clear that this huge increase in alerts makes real-time protection more important than ever.

AI tools and automated attacks are being used extensively by hackers and state-sponsored attackers – so the only way to fight back is with an AI-powered SIEM platform that can match their speed and sophistication.

There are two approaches to achieving this: a total transformation, or a gradual transition.

Strategy #1: Rapid transformation

By totally transforming your SIEM, you can rebuild your security operations in a ‘big bang’ that ensures you’re up to standard and prepared for the future in the shortest time possible.

Switching to Singularity SIEM ‘in one go’ involves some commitment and changes in working methods, but it also gives you a faster ROI.

Also, time is saved with hyperautomated workflows, and you achieve real-time AI-powered protection very quickly.

Strategy #2: Gradual transition to match your pace

Another approach is to augment and integrate SentinelOne’s cloud-native Singularity SIEM into your SOC in a phased approach.

This allows you to make incremental gains while keeping your current workflows.

It’s built on the Singularity Data Lake, and, because it uses an open ecosystem, SentinelOne’s Singularity SIEM can ingest data from structured and unstructured first and third-party data sources.

It means you’re never restricted by vendor lock-in and can easily integrate it with your current stack.

This way, you can filter, enrich, and optimize your legacy SIEM data and start using AI-based real-time protection.

What’s different about Singularity SIEM?

• Total coverage – All your cloud environments, endpoints, networks, identities, emails, and much more, in one solution. Autonomous machine-speed detection gives real-time protection and ultimate visibility.
• Blazing speed and massive scale – Compared to legacy SIEM solutions, SentinelOne’s AI-powered Singularity SIEM is 100 times faster. You can also store exabytes of data for as long as you need it.
• Open – You can ingest data from first-party and third-party sources and easily integrate it with your entire security stack.
• Lower costs – As well as giving your SecOps team more time, Singularity SIEM has a 50% lower operational cost, and 246% ROI based on the total cost of ownership. This comes with a 99% reduction in risk exposure too, so the benefits are tangible.
• Intelligent automation – By combining AI with automated workflows, you can replace your brittle SOAR workflows and rulesets with real intelligence. AI-driven detection and efficient algorithms hyperautomate your investigation and response, using human governance to the best effect.

The advantages of an autonomous SOC

Security teams are caught between two powerful forces. On one hand, there’s a growing volume of highly sophisticated attacks. These use AI and automation to penetrate complex cloud environments, devices, and applications at an unprecedented rate.

And, on the other, there’s a chronic shortfall of time, resources, and expertise. There was a shortage of 4 million cybersec professionals last year, and this trend is continuing. So, you must allocate resources effectively and reduce unnecessary manual work for your team.

Singularity AI SIEM gives you the opportunity to transition to an autonomous SOC, on your own terms.

As well as learning and adapting to new threats, it accelerates your responses with step-by-step guidance from automated playbooks – so you always have an effective and validated response ready for any scenario.

It also intelligently analyzes vast amounts of data, using the most complete threat and vulnerability intelligence available. This reduces false positives and finds patterns or anomalies that many legacy SIEM solutions would miss.

Perhaps the greatest impact comes from enhancing your SOC with autonomous capabilities, so you can always operate at peak efficiency.

By automating the bulk of your repetitive tasks and workflows, the need for manual intervention is greatly decreased – and those valuable cybersecurity professionals in your team can be used more effectively.
