Insider Threat Pulse Report

Why Insider Threats Deserve a Fresh Look in 2025

Insider threats have moved from theoretical to unavoidable. SpyCloud’s Insider Threat Pulse Report 2025, based on a survey of 100 security leaders, reveals that over half of organizations (56%) experienced at least one insider-related incident in the past year. It’s pretty clear that insider risks are now the rule rather than the exception.

Across the board, leaders express concern. Nearly all (97%) point to negligent insider threats as a concern, and 93% are concerned about malicious insider threats.

Yet despite the level of risk, the gap between intent and action remains wide. Many organizations claim to have insider threat programs, but the research shows that these efforts are often reactive, fragmented, and overly dependent on late-stage behavioral detection.

This article takes a deep dive into some of the report’s most significant findings and explains why identity-first detection is the missing piece in most insider risk strategies.

Insider risk is evolving and programs are not keeping up

The definition of “insider threat” has broadened. It no longer refers only to a disgruntled employee leaving a company on bad terms.

Today it can include:

Compromised insiders are often the hardest to detect. Their actions look legitimate until a hijacked account is used to escalate privileges or move laterally inside the network. Traditional behavioral tools often struggle to catch these cases in time.

Although 64% of organizations say they have insider threat programs, most rely heavily on behavioral analytics. These tools only alert defenders after risky activity has started, which is too late to prevent damage.

Why today’s insider threat signals come too late

When asked what warning signs they monitor, security leaders identified five red flag indicators:

Anomalous behavior

Unusual logins, deviations from baseline activity, or data exfiltration attempts

Excessive downloads

Abnormal transfers of sensitive files outside the scope of a role

Unauthorized access attempts

Efforts to escalate privileges or reach restricted systems

Suspicious network activity

Unexpected connections or promiscuous internet use

Some organizations also track background check anomalies or stressors such as financial hardship, but these are viewed as secondary indicators.

The problem is that these signals usually appear after an insider has already acted. A terminated employee showing hostility or a contractor suddenly accessing sensitive systems is not the beginning of a problem. It is proof that the threat is already active.

Where insider threat programs stall: detection, visibility, and response

Even with insider threat programs in place, organizations face persistent challenges that keep them from responding quickly and effectively:

“Teams are inundated with telemetry and overwhelmed by noisy alerts, making it difficult to piece together a coherent picture.”

These barriers explain why insider programs remain reactive. Without earlier signals and stronger collaboration, defenders often find themselves playing catch-up.

Infostealer malware silently fuels compromise

One of the pressing threats facing organizations today is the rise of fraudulent IT worker campaigns linked to North Korea. These operations involve state-sponsored actors applying for remote jobs using stolen or fabricated identities. Once inside, they can exfiltrate intellectual property, generate revenue for sanctioned regimes, or enable broader cyber operations.

SpyCloud research confirmed this trend by uncovering self-infection data from DPRK IT workers who inadvertently exposed their own activities through commodity infostealer malware. This analysis revealed the extent of the campaign – reaching into Fortune 500 companies and beyond – and showed how traditional HR and security processes often fail to detect fraudulent applicants.

The Insider Threat Pulse Report 2025 highlights the challenge organizations face in responding to this threat:

Charles Carmakal, CTO of Mandiant Consulting, describes the scale of the problem:

“Nearly every CISO that I’ve spoken to about the North Korean IT worker problem has admitted they’ve hired at least one North Korean IT worker, if not a dozen or a few dozen.”

This trend proves that insider risk is not only a workforce issue. It is a geopolitical security concern that requires tighter screening and identity-first detection.

Identity exposure: the missing early warning signal

Behavioral analytics like UEBA and DLP are useful, but they are late-stage tools. They flag anomalies only once suspicious actions are visible.

The earliest warning signs of insider threats often come not from behavior but from identity misuse. Malware infections and stolen credentials typically surface on the darknet well before any red flags appear inside the enterprise.

SpyCloud’s identity intelligence equips security teams with the earliest possible warning. With access to recaptured data, teams can:

This approach transforms insider defense from reactive monitoring into proactive prevention.

Four priorities for closing the insider threat defense gap

To stay ahead of insider threats, security leaders should implement the following steps:

Final thoughts: Spot risks sooner. Defend smarter.

Insider threats extend from compromised identities, to fraudulent applicants, to state-sponsored infiltration campaigns. The Insider Threat Pulse Report 2025 makes three things clear:

SpyCloud provides security leaders with identity intelligence that enables earlier detection, reduces noise, and connects HR and security workflows. Instead of reacting to insider threats after they emerge, organizations can finally get ahead of them.

The future of insider defense is proactive, identity-first, and automated. SpyCloud helps you get there.

FAQs

The report draws on a survey of 100 security leaders, including 50 CISOs and 50 security managers or directors, from organizations with 500 or more employees. It explores how these professionals perceive, detect, and respond to insider threats.

SIEM platforms remain the backbone of most programs. Leaders also use DLP, UEBA, and EDR tools for added visibility. HR and identity data sources are sometimes included, but integration is usually inconsistent and often manual. Security teams should incorporate identity intelligence to strengthen their toolkit.

Most insider threat programs are not enough because they wait until it is too late. Behavioral analytics only flag activity after it becomes suspicious, leaving teams stuck in reaction mode. With analysts already facing noisy alerts, limited resources, and resistance from within the organization, prevention is almost impossible.

SpyCloud introduces identity intelligence as an early warning system. By analyzing recaptured data from malware infections, phishing campaigns, and breaches, SpyCloud uncovers compromised identities and fraudulent applicants before behaviors turn risky. This fills the gap left by traditional behavioral tools.

The report provides credible survey-backed data. It highlights the scale of the problem, the shortcomings of current programs, and the impact on security teams. These statistics give leaders the evidence they need to secure executive and board-level buy-in for investment in earlier detection and automation.
