6 critical mistakes that undermine cyber resilience (and how to fix them)

Silos are the enemy of business resilience. As IT leaders, we’ve all felt the pain: the backup administrator, SOC analyst, and endpoint engineer operating in separate worlds—often meeting for the first time in the chaos of a live cyberattack. The result? Delayed responses, missed signals, and greater impact on the business.

The N-able 2026 State of the SOC Report leaves no doubt. In just one year, 18% of all security alerts came from network and perimeter exploits—risks many endpoint-only teams never saw coming. Even scarier? 50% of attacks completely bypass endpoint controls. You can’t afford to be siloed. Here’s where most organizations go wrong—and the six crucial steps you need to take to align our teams, tools, and processes for true business resilience.

Mistake 1: Unclear roles and responsibilities

Confusion creates costly delay. During an incident, who owns quarantine actions on high-value endpoints? Who can take critical apps offline? Without a detailed, cross-team RACI matrix (Responsible, Accountable, Consulted, Informed), response efforts stall and attackers gain precious minutes.

Fix: Build a unified RACI for incident response and disaster recovery. Everyone from endpoint to SOC to backup should know their duties in a crisis. Learn how different personalities affect cyber crisis response in this Guide to Managing Strong Personalities During a Cybercrisis.

Mistake 2: Fragmented asset and risk views

Fragmented asset and risk views make it difficult for teams to understand what is actually in their environment and where the most pressing exposures reside. When devices, configurations, and identity data live in separate tools or are maintained inconsistently, gaps appear that attackers can exploit. This lack of a unified perspective slows decision making, complicates prioritization, and obscures the relationships that matter most during an investigation or response.

Fix: Create a single, reliable view of assets and risks across the entire environment. Consolidating inventories, vulnerability data, and identity insights helps teams quickly see what they have, how it is behaving, and where risk is concentrated. With a unified source of truth, organizations can prioritize more effectively, enforce policies consistently, and respond with greater confidence.

Mistake 3: Policies and playbooks that don’t talk to each other

Our State of the SOC report found that 18% of alerts now originate from the network edge, which is a significant shift from previous years. If the SOC keeps logs for 90 days, but IT rotates them every 30, the evidence of those attacks may be lost forever. Gaps like this lead to missed detection and slow recovery.

Fix: Align policies, retention schedules, and playbooks across security and IT. Aligning evidence ensures alerts can be fully investigated. Establishing unified standards for log retention, data sources, and workflow handoffs ensures that every team is operating from the same information and timeframes. When policies are coordinated and playbooks are connected, organizations can detect edge‑based attacks more reliably and accelerate recovery with complete, consistent evidence.

Mistake 4: Disconnected tools prevent timely action

The best-intentioned teams are blocked when they operate in silos. Our research shows a 5x year-over-year jump in automated response actions (SOAR), but unless EDR, backup, and SOC tools integrate, you can’t leverage this automation at scale.

Fix: Invest in integrating toolsets and automating workflows. For example:

• EDR detects ransomware and triggers automated isolation.
• Backup systems auto-scan restore points for malware before allowing recovery.
• Failed backup alerts create tickets in both security and endpoint queues.

By breaking down the data silos, you move from reaction to prevention. Looking for ways to automate at scale? This Playbook for Smarter Automation offers practical steps and scripts to take your IT security team to the next level.

Mistake 5: No cross-team drills or incident simulations

A playbook only works if everyone’s practiced. Too often, organizations run isolated tests—file restores here, pen tests there—but rarely do we rehearse the full detection-through-recovery scenario.

Fix: Schedule regular tabletop exercises involving endpoint, SOC, and backup teams. Scenarios pulled from the State of the SOC Report, like holiday weekend ransomware, are essential for exposing process gaps before real attackers do. Planning and preparing are key. Here are some best practices when it comes to planning a tabletop exercise.

Mistake 6: Measuring success in silos

If the backup team meets its targets, but recovery takes three days because detection lagged, the business still suffers. The SOC’s speed means little if the restored data is compromised.

Fix: Track success with unified, resilience-focused KPIs. For example:

• Mean Time to Recover (MTTR): How quickly can we restore critical systems after an attack?
• Patching SLA compliance: Not just an IT metric, but key to threat prevention.
• Successful recovery testing: Are we validating backups or just assuming they work?
