Security | Threat Detection | Cyberattacks | DevSecOps | Compliance

A security alert rarely fails because the team lacks data. It fails because the data is scattered. At 2 a.m., that usually looks familiar. The firewall has one timestamp format. The domain controller has another. The cloud console keeps the event you need behind three menus. The application server writes plain text that only one engineer knows how to read.

Most healthcare security teams don't start thinking about HIPAA automation because they love compliance tooling. They start when another audit request lands, someone asks for six months of access reviews, policy attestations are out of date in three different folders, and the security team spends a week reconstructing evidence that should already exist. The problem isn't that teams don't understand HIPAA.

Adversaries are using AI to launch cyber attacks in record time, forcing security teams to measure responses in seconds instead of hours or days. Detecting these attacks is increasingly difficult. Phishing campaigns built by large language models (LLMs) achieve click-through rates 4.5x higher than traditional methods.1 Public sector organizations are at an inflection point with cybersecurity. Most security stacks in place today weren’t built for this level of speed.

A lot of teams are in the same spot right now. Users say the VPN feels unstable, finance reports timeouts in a cloud app, a firewall throws intermittent alerts, and nobody can tell whether the problem is congestion, a misconfigured interface, a failing device, or something hostile moving through the network.

Most security platform comparisons begin and end with the wrong number. Two vendors submit proposals. One comes in lower. Finance notes the delta, flags the savings, and the conversation shifts. What rarely makes it into that comparison is everything that determines what the platform actually costs once deployed, staffed, scaled, and operating effectively in production. That gap between sticker price and real cost is where security investment decisions quietly go wrong.

There is a huge amount of excitement right now about AI and security operations. Across the industry, we are seeing rapid innovation in areas such as behavioural analytics, AI-assisted investigation, and increasingly agent-based capabilities designed to help security teams process large volumes of activity more effectively. Security teams need that help. The scale of alerts, identities, and telemetry they must manage today has grown far beyond what humans alone can realistically handle.

Security teams ingest massive volumes of telemetry from endpoints, cloud workloads, identity providers, and network controls. The goal is faster threat detection and shorter incident response times. But the reality is that all of this data becomes harder to move, slower to query, and messier to analyze as it grows. That's data gravity, and it's the biggest barrier to effective AI in cybersecurity.

In the public sector, it’s not uncommon for disruptions of critical infrastructure to ripple outward and wreak major havoc on systems and communities whether the cause is a technical issue, a natural disaster, or a cyber attack. As critical infrastructure becomes more connected through distributed systems and IoT devices, the attack surface continues to expand.

Analyst reports tell you what vendors do. Peer reviews tell you whether it actually works. The Gartner Peer Insights Voice of the Customer for SIEM is built on verified reviews from real security and IT practitioners who bought, deployed, and operated the platforms they rated. No vendor involvement in the scoring. No pay-to-play placement. Just practitioners saying what worked and what did not. Graylog was included in the 2026 edition of that report. Here’s what our users said.
