Navigating the New Landscape of Insider Threats: Insights from a Global Cybersecurity Report

In an evolving digital landscape, insider threats have shifted dramatically, now surpassing external attacks as the primary concern for organizations worldwide. A recent comprehensive study from Exabeam reveals alarming trends that underline the urgent need for organizations to rethink their cybersecurity strategies. With AI acting as a catalyst for both risks and responses, understanding the dynamics of insider threats is more critical than ever.

The Emergence of Insider Threats

Based on a global survey of over 1,000 cybersecurity professionals, Exabeam’s findings indicate that 64% of respondents now consider insiders—whether intentionally harmful or inadvertently compromised—as a greater risk than their external counterparts. This shift is significantly influenced by advancements in generative AI (GenAI) technologies, which have made attacks faster and more elusive. As Steve Wilson, Exabeam’s Chief AI and Product Officer, aptly notes, “Insiders aren’t just people anymore; they’re AI agents logging in with valid credentials, spoofing trusted voices, and making moves at machine speed.”

The Steep Rise in Insider Incidents

The report uncovers a concerning trend: 53% of organizations have observed an increase in insider incidents over the past year, with a majority (54%) anticipating this rise will continue. Particularly vulnerable sectors include government entities, with 73% expecting heightened risks, followed closely by manufacturing (60%) and healthcare (53%). The surge in insider activity can be attributed to both malicious intent and unintentional compromises, as access to sensitive information expands.

A Global Perspective on Risk

Interestingly, the risk landscape is not uniform across the globe. The Asia-Pacific and Japan regions exhibit the most significant potential for insider threat growth at 69%, driven by an increase in identity-driven attacks. Conversely, nearly 30% of organizations in the Middle East foresee a decrease in insider threats, raising questions about their confidence in existing defenses or possibly indicating a dangerous underestimation of risk.

The AI Factor

AI’s role in this landscape cannot be overstated. It serves as a force multiplier for insider threats, enhancing the efficiency and subtlety of harmful activities. Alarmingly, the two leading vectors for insider attacks are now AI-related, with 27% of cybersecurity professionals highlighting AI-enhanced phishing and social engineering as the most pressing concerns. These tactics demonstrate an alarming capability to evolve in real-time, mimicking legitimate communications and exploiting established trust.

Adding complexity to this scenario is the unauthorized use of GenAI, which poses a dual risk: tools aimed at improving productivity can also be misused for malicious purposes. In fact, 76% of organizations report instances of unapproved GenAI usage, with technology, financial services, and government sectors witnessing the highest rates. For the Middle East, where unauthorized GenAI use is a major concern at 31%, this highlights the urgent need for robust governance and strategic oversight.

The Gaps in Security Programs

Despite the high percentage of organizations claiming to have insider threat programs—88%—most fall short in the essential area of behavioral analytics, crucial for early detection of abnormal activity. Only 44% of respondents utilize user and entity behavior analytics (UEBA), which should be foundational for identifying subtle or emerging threats. Many organizations lean heavily on traditional security measures like identity and access management, yet these often lack the behavioral context necessary for effective threat detection.

AI tools are present in a staggering 97% of organizations, yet there is often a disconnect between deployment and actual readiness. Many executives believe these tools are fully utilized, while managers on the ground report that many are still in pilot phases. Security teams face persistent obstacles, including privacy concerns, fragmented toolsets, and difficulties interpreting user intent, which hamper their ability to combat insider threats effectively.

The Need for a Paradigm Shift

Kevin Kirkwood, CISO at Exabeam, emphasizes the urgency of this situation, stating, “AI has added a layer of speed and subtlety to insider activity that traditional defenses weren’t built to detect.” He stresses that although security teams are increasingly deploying AI for threat detection, the absence of strong governance poses significant challenges.

As insider threats become more pronounced, propelled by AI and identity misuse, organizations can no longer rely on outdated defense mechanisms. Progress necessitates alignment between leadership priorities and operational realities, urging businesses to adopt a more contextualized approach that differentiates between human and AI-driven actions.

Towards a Collaborative Future

Addressing the complexities of insider threats will require more than mere policy updates. It demands cross-functional cooperation and governance models that evolve in tandem with AI’s rapid adoption. Success will hinge on the ability to shorten detection and response times, eliminate the window of opportunity for insider activities, and dynamically adjust strategies as threats evolve.

As the cybersecurity landscape continues to change, organizations that proactively adapt will not only safeguard their assets but will also foster an environment of trust and collaboration, essential for navigating today’s multifaceted threat terrain.
