External cyberattacks, especially ransomware, are now viewed as a matter of when, not if.
It’s no wonder they dominate cybersecurity discussions and make frequent headlines.
IBM’s 2025 Cost of a Data Breach report found that the average global cost of a data breach stands at $4.4million, underscoring why the threat of an attack keeps business and IT leaders up at night.

But they represent only one side of the data risk landscape. What’s less understood and often underestimated are the internal threats that can be just as disruptive and damaging.
From simple employee errors to deliberate insider actions, and even the unintended consequences of generative AI tools, these risks pose serious challenges for every organization’s data security strategy.
Human Error and Malice
Human error remains one of the most persistent vulnerabilities in cybersecurity. In fact, 2024 research found that the human element played a role in 68% of breaches, ranging from simple mistakes to social engineering and misconfigurations. Ignoring this reality leaves a critical gap in any security strategy.
Human error isn’t the only internal risk. Insider threats – both intentional and negligent – represent a growing portion of today’s breach landscape. In fact, 83% of organizations experienced at least one insider-related incident last year. Whether it’s a disgruntled employee exfiltrating data or a staff member mistakenly over-provisioning access, incidents involving trusted credentials are notoriously difficult to detect and recover from.
Whether it’s accidental human error or deliberate insider attacks, the first step to reducing these types of risks is to acknowledge that the weakest link in any cybersecurity chain is people. Even the most advanced internet security infrastructure can be compromised by a single careless mistake or a trusted user with bad intentions. Creating a culture of continuous education mixed with accountability can mitigate some of these threats.
Reducing privileged access to only what is necessary can also significantly lower the risk of employee caused data leaks. However, organizations should always assume that human errors will occur and prepare accordingly. User and Entity Behavior Analytics (UEBA) plays a critical role in identifying suspicious activity that may indicate insider threats.
By flagging anomalies such as unexpected data transfers or unusual access patterns, UEBA enables security teams to respond swiftly before significant damage occurs.
Just as important is having strong technical safeguards in place. These act as a critical safety net when human controls fail. For example, it’s important to verify that automated backups are running efficiently and include all data sources, such as cloud applications and endpoints.
This can ensure that no critical data is left unprotected or overlooked in the event of a disruption or breach. These backups need to be immutable and tamper-proof, so that even a rogue insider cannot alter or delete recovery points.
The AI Conundrum
While AI promises a boost to productivity and innovation, it also brings with it new threats. As an example, the rise of AI co-pilots and agents in various workflows such as coding, writing and data analysis widens the attack surface. For AI to operate efficiently, it requires access to sensitive internal data such as documents and proprietary systems, which means that the slightest oversight in access permissions and data governance can severely cost an organization.
This is not going unnoticed. The U.S. National Institute of Standards and Technology (NIST) states in its AI Risk Management Framework that AI models may “leak, generate, or correctly infer sensitive information” even data not explicitly included in the input, through memorization, adversarial attacks, or by combining disparate sources.
This concern is echoed in the private sector, with over 80% of security leaders expressing concern that generative AI could leak company secrets, and security experts warning that only 24% of generative AI initiatives are fully secured. Furthermore, a staggering 90% of organizations report a lack of adequate security standards to defend against AI-centered threats. Gartner predicts that by 2027, more than 40% of AI-related data breaches will be caused by the improper use of generative AI.
So how can enterprises continue to implement the evolving world of AI into business processes while ensuring it doesn’t open the door to a bevy of cyberattacks? The first step is to treat AI agents as part of the threat model. The same security principles that are often implemented to traditional IT environments need to be applied to AI implementation – zero trust, data minimization, encryption, segmentation, etc.
AI agents need to be viewed as tools with privileged access, and handled accordingly. The data that is being fed into these AI agents needs to be reviewed and cleaned-up, including removing outdated or overly sensitive files from training sets and ensuring only approved data sources are utilized.
Close monitoring and keeping a log of all AI interactions is also critical. This needs to be detailed enough to enable an audit trail that can help to detect potential abuse or oversharing of confidential data.
To reduce the risk of human error, AI guidelines should also include security awareness training so that employees can understand that AI agents are not sandbox environments, and any sensitive data could be logged, stored, and in the worst-case scenario, shared.
Immutable Backups Delivered as a Managed Service
While the threat landscape continues to expand, the reality is clear – no security stack is impenetrable. Cybercriminals will always search for new angles, whether through ransomware, insider threats, or AI-driven exploits. That’s why true resilience depends not only on prevention but also on the ability to recover quickly and confidently when defenses are breached.
Immutable backups, delivered as a managed service, provide that safety net. Unlike traditional backups that can be corrupted, deleted, or encrypted by attackers, immutable backups are unchangeable and tamper-proof. By layering this with 24/7 monitoring, expert management, and tested recovery processes, a managed service ensures that recovery points remain secure and always available.
This approach dramatically shortens downtime, from days to hours and removes the operational burden from internal IT teams who may lack the time or expertise to manage complex recovery environments.
