A company's attack surface grows with every new cloud service, every new integration, and every additional device. Heading into 2026, it's clear that security needs to be treated as an ongoing process rather than a one-off project.
Identity protection remains a central theme. Classic perimeter security is losing relevance, while access control at the level of individual users, devices, and applications is becoming more important. Companies that don't regularly review access rights quietly accumulate risk over the years.
Supply chain security is also moving further into focus. Modern software is made up of many third-party components — from open-source libraries to external APIs. A resilient security strategy has to make these dependencies visible instead of ignoring them.
At the same time, the attacker side is changing: automated attack tooling is lowering the barrier to entry for attacks on smaller and mid-sized companies, which used to be targeted less often. Security practices that once made sense only for large enterprises are becoming relevant for the mid-market too.
In concrete terms, that means: regular audits instead of one-off checks, clearly documented responsibilities for when something goes wrong, and a security culture that extends beyond the IT department. Technology alone doesn't solve a security problem if processes and ownership are missing.
