According to the Arctic Wolf 2026 Threat Report, this imbalance is already shaping how attacks happen and how organisations need to respond.

The Shift from “Break In” to “Log In”

One of the clearest takeaways is a fundamental change in attacker behaviour.

Rather than forcing their way into networks, attackers are increasingly logging in using:

• Stolen credentials

• Compromised identities

• Legitimate remote access tools such as RDP and VPN

These actions often look like normal activity. Traditional security controls, built to detect obvious threats, struggle to identify this behaviour.

The result is a quieter, harder-to-detect breach that can go unnoticed until damage is already done.

92% of Incidents Come Down to Three Threats

Arctic Wolf’s data shows that the vast majority of incidents fall into three areas:

• Ransomware

• Business Email Compromise (BEC)

• Data extortion

Together, these account for 92% of incident response engagements.

What is changing is how these attacks are executed.

Data-only extortion is rising, where attackers steal sensitive information without encrypting systems. This reduces visibility and increases pressure on organisations to respond quickly.

At the same time, phishing remains the primary entry point, driving the majority of BEC incidents.

Attackers Are Timing It Right

Cyber attacks are no longer confined to working hours.

Arctic Wolf’s research found:

• 51% of alerts occur outside standard business hours

• 15% happen at weekends

Attackers understand that many organisations lack round-the-clock monitoring. They exploit these gaps to gain access, escalate privileges and move laterally before anyone notices.

Why Traditional Security Operations Are Struggling

Most organisations are not lacking tools. They are lacking the ability to operationalise them effectively.

Security teams are dealing with:

• High volumes of telemetry across cloud, SaaS, endpoint and network environments

• Alert fatigue caused by false positives

• Limited internal resource to investigate and respond quickly

The challenge is no longer just visibility. It is prioritisation and speed.

Where AI Is Making a Real Difference

Arctic Wolf positions AI as a way to solve the scale problem in modern security operations.

Not by replacing people, but by enabling them to work faster and more effectively.

AI is now applied across the full threat detection, investigation and response lifecycle:

Detection

• Identifying anomalies in login patterns and user behaviour

• Detecting phishing and credential misuse

• Correlating weak signals that would otherwise be missed

Investigation
Linking events into a coherent incident, mapping activity to known techniques and adding context around users, devices and risk.

Response

• Recommending containment actions

• Automating routine workflows

• Reducing time to respond and contain threats

At scale, this reduces noise significantly. Arctic Wolf reports a reduction of over 99.9% from raw telemetry to actionable alerts.

Why Identity Is Now the Critical Battleground

A key theme throughout the report is the growing importance of identity security.

With attackers using valid credentials, many breaches now bypass traditional perimeter controls entirely.

This makes it essential to monitor:

• Authentication patterns

• Privileged access behaviour

• Lateral movement across systems

These signals are often invisible to legacy tools, particularly when activity blends in with normal usage. This is where AI-driven behavioural analysis becomes critical.

AI Alone Isn’t the Answer

While AI is becoming foundational, it is not without risk.

Key challenges include:

• Poor data quality leading to unreliable outputs

• Models needing to adapt as environments change

• Lack of explainability reducing trust

• Over-automation disrupting operations

• Privacy and governance requirements

The most effective approach combines AI with human expertise.

What This Means for UK Organisations

The 2026 Threat Report highlights a simple reality:

Cybersecurity is no longer just about prevention, it is about speed.

Organisations relying on default configurations, limited monitoring hours and disconnected tools are more likely to experience a breach and take longer to respond.

The focus needs to shift towards:

• Continuous monitoring

• Rapid detection and investigation

• Consistent, well-managed response

At Netprotocol, with over 25 years in business and decades of experience across our team, we see Arctic Wolf’s 2026 Threat Report reinforcing a clear shift in cybersecurity.

The question is no longer whether an organisation will face an attack, but how quickly it can detect and respond to it. AI is a key part of that answer, but only when it is implemented with the right data, processes and expertise behind it.
