People remain the most targeted element of any organisation's attack surface. Technology controls have matured considerably over the past decade, yet attackers have responded by focusing their efforts on the one variable that firewalls and filters cannot fully contain, which is human behaviour. For chief information security officers, reducing human cyber risk is no longer a soft, secondary concern but a strategic priority that sits alongside infrastructure hardening and incident response, at the very centre of a modern security programme.
The overwhelming majority of successful breaches involve a human element, whether that is a member of staff clicking a malicious link, reusing a weak password, mishandling sensitive data or being manipulated through social engineering. A single convincing email can bypass millions of pounds of technical investment in seconds. This is why forward-thinking security leaders are treating their people as a genuine layer of defence rather than a vulnerability.
The encouraging news is that human risk is measurable, manageable and reducible. With the right combination of culture, training and measurement, organisations can transform their workforce from the most exploited part of the business into a resilient, vigilant first line of defence. Below are six proven tactics that every CISO should adopt in 2026 to lower human cyber risk meaningfully and sustainably.
1. Make awareness continuous, not occasional
The single most common mistake organisations make is treating security awareness as an annual tick-box exercise. A once-a-year session, often delivered as a lengthy slideshow that staff rush through to reach a completion certificate, does very little to change day-to-day behaviour. Knowledge fades quickly, threats evolve constantly and a single annual touchpoint simply cannot keep pace with the way attackers operate.
The far more effective approach is to replace those annual sessions with ongoing, engaging cyber security awareness training that keeps security front of mind throughout the year. Short, frequent and relevant content delivered in manageable doses helps employees retain what they learn and apply it instinctively. When awareness becomes a steady habit rather than a rare event, people are far more likely to recognise a threat in the moment that matters.
Continuous training also allows you to respond to emerging threats in near real time. If a new scam is circulating, you can deliver a timely module within days rather than waiting for next year's refresher. This agility is essential in a landscape where the nature of a cyber attack can shift from one quarter to the next.
2. Run realistic phishing simulations
You cannot improve what you do not test and regular phishing simulations build real world instincts and reveal precisely where additional support is needed. By safely exposing employees to the kinds of deceptive emails they are likely to encounter, you give them the practice they need to spot the warning signs before a genuine attacker comes knocking.
The key word here is realistic because simulations that are too obvious teach people very little, while overly punishing tests can damage trust and morale. The goal is to mirror the tactics that real adversaries use, including urgency, authority and familiarity, so that staff learn to pause and scrutinise, rather than react. Over time, repeated exposure rewires instinct and the click rate on malicious links falls steadily.
Just as importantly, simulations generate the data you need to target your efforts. They highlight which departments, roles or individuals would benefit from extra training and in what areas, allowing you to focus resources where they will have the greatest effect, rather than spreading them thinly across the whole organisation.
3. Strengthen anti-phishing defences
Phishing remains the most prolific entry point for attackers, so it deserves dedicated attention. The most resilient organisations combine technology with focused anti-phishing training to reduce susceptibility to email based attacks, such as business email compromise. Technical controls like email filtering and authentication protocols catch a large volume of threats, but the most sophisticated messages are designed specifically to slip past them, which is exactly why the human layer is so important.
Business email compromise is a particularly costly threat because it relies on manipulation rather than malware. An attacker might impersonate a senior executive or a trusted supplier and request an urgent payment or a change to bank details. There is often no malicious attachment for a filter to catch, only a carefully worded message engineered to bypass email security filters to exploit trust and apply pressure. Training staff to verify unusual requests through a separate channel can prevent losses that no technical control would have stopped.
Effective anti-phishing work also extends beyond email to the broader picture of online security awareness training, helping employees stay alert to threats across the web, social platforms and messaging tools that attackers increasingly exploit.
4. Protect sensitive data at every touchpoint
Data is among the most valuable assets any organisation holds and it is also one of the easiest to compromise through simple human error. A misaddressed email, an unsecured file share or a document left accessible to the wrong people can cause as much damage as a deliberate cyber attack. Equipping staff with proper data security awareness training ensures they handle information safely wherever they work.
With hybrid and remote working now firmly established, the perimeter of the organisation has expanded into homes, cafes and personal devices. Employees need to understand how to classify information, how to store and share it securely and what their responsibilities are under data protection regulation. When people understand both the why and the how, secure behaviour becomes second nature rather than an imposition.
Good data practice also reduces the impact of any incident that does occur. If staff consistently apply the principle of least privilege and avoid storing sensitive data where it does not belong, a breach is contained more easily and the potential damage is limited.
5. Build a no-blame reporting culture
Technology and training will only take you so far if your people are afraid to speak up. One of the most powerful things a CISO can do is encourage fast, fearless reporting so that threats are contained before they spread. When an employee suspects they have clicked something they should not have, the speed of their response often determines whether the event becomes a minor blip or a major incident.
Unfortunately, a culture of blame drives the opposite behaviour because if people fear punishment or embarrassment, they are more inclined to hide their mistakes and that delay gives attackers the time they need to escalate the breach. By contrast, a no-blame culture treats every report as a valuable early warning and thanks people for raising the alarm, even when it turns out to be a false alarm.
This cultural shift is a core part of effective human risk management because reducing risk is not only about teaching people what to do, it is about creating an environment where doing the right thing feels safe and supported. When reporting is celebrated rather than penalised, your workforce becomes an early detection system that no automated tool can replicate.
6. Measure and communicate progress
What gets measured gets managed and to sustain investment and momentum, CISOs need to track behaviour change over time and report risk reduction to the board in terms that resonate with business leaders. Vanity metrics such as the number of training modules completed actually tell you very little about behavioural resilience. The metrics that matter show how company behaviours are shifting, whether that is a falling phishing click rate, faster reporting times or a rising proportion of staff who recognise and report simulated threats.
Presenting this data clearly to the board does two things: It demonstrates the tangible value of your security programme and it keeps human risk on the board's strategic agenda, where it belongs. When leaders can see risk falling quarter on quarter, they are far more likely to continue backing and funding the initiatives or programmes that deliver those results.
Measurement also closes the loop because the insights you gather feed directly back into the first five tactics, helping you refine your training, target your simulations and focus your cultural efforts where they will have the greatest impact. In this way, tactics work together as a continuous cycle of improvement rather than a list of isolated activities.
