Shadow IT: Security and compliance risks

We frequently observe among our clients that balancing (digital) operational flexibility with security and compliance is a significant challenge. A well-known issue and risk in this context is Shadow IT, or the use of unauthorized systems, applications, and devices within an organization’s network. While often driven by the need for increased efficiency, Shadow IT introduces considerable risks that can undermine security, regulatory compliance, and operational stability.

The Origins

Shadow IT arises when employees bypass IT approval processes to use tools that better meet their immediate needs. The rise of online software and platforms has amplified this issue, as cloud-based solutions are easily accessible and quick to adopt without IT oversight. Examples include sharing sensitive files through personal Dropbox accounts or collaborating in unauthorized project management tools such as Trello or Asana. Remote working has further exacerbated this phenomenon, with employees increasingly using personal devices and apps to perform their duties, often beyond the organization’s visibility. While these tools may seem practical, they come at the expense of security visibility and control.

The Risks

From a cybersecurity perspective, Shadow IT significantly increases the attack surface for hackers or malware. Unauthorized software or devices often bypass critical security measures such as encryption, multi-factor authentication (MFA), and logging. Endpoint Detection and Response (EDR) solutions often lack visibility into these tools, making it harder for IT teams to detect vulnerabilities and threats. Moreover, these tools frequently contain weaknesses, such as 0-day vulnerabilities, making them an attractive target for attackers and a potential entry point into the broader network.

The Consequences

The potential consequences of Shadow IT extend beyond security. Strict regulatory frameworks like GDPR, HIPAA, and DORA require organizations to handle sensitive data with precision when processing, storing, and transferring it. Unauthorized tools fall outside formal processes and may breach these regulations, such as by storing data in unauthorized locations or exposing it to unapproved third parties. Imagine sensitive client data being uploaded to a cloud service without the appropriate geographical restrictions or security controls—this can lead to fines, legal action, and reputational damage. For financial institutions subject to regulations like DORA, Shadow IT can hinder compliance with requirements around resilience and operational risk management.

Fragmentation

Shadow IT also introduces operational inefficiencies. Employees who independently choose tools create fragmentation across systems and processes. IT departments lose oversight of application usage, complicating integration and support. This fragmentation often results in redundancy, where multiple tools perform the same function, leading to unnecessary costs. Without a centralized IT structure, a disjointed landscape emerges, undermining strategic goals and significantly increasing risks.

Mitigating Shadow IT

Monitoring and Detection

To mitigate Shadow IT risks, organizations must adopt a proactive approach. Visibility is the cornerstone of any mitigation strategy. There are multiple solutions available to monitor and control Shadow IT. Tools such as Network Traffic Analysis (NTA) and SIEM solutions can help detect anomalous behavior that may indicate the presence of unauthorized tools or devices.

IT Management

Beyond detection, it’s essential to address the underlying causes of Shadow IT. Often, employees lack access to approved tools that meet their needs. IT departments can resolve this by engaging with employees to understand their requirements and offering secure, compliant alternatives aligned with business objectives. Streamlining the IT procurement process makes it easier for teams to request new tools without resorting to unofficial solutions. Education also plays a significant role: employees must be aware of the risks posed by unauthorized tools, such as data breaches, compliance issues, and increased exposure to cyberattacks.

Advanced Solutions

An advanced strategy involves implementing a Zero Trust Architecture. Zero Trust assumes that no application, user, or device can be inherently trusted. By enforcing granular access controls, organizations can ensure that only authorized tools gain access to sensitive data and systems. Combined with stringent Identity and Access Management (IAM) measures, this approach minimizes the likelihood of Shadow IT becoming a gateway for attackers. Read more about Zero Trust in our blog.

In Summary

While Shadow IT may offer short-term benefits, the long-term risks far outweigh them. By expanding the attack surface, creating compliance challenges, and introducing operational fragmentation, Shadow IT poses a significant risk to modern organizations. A combination of visibility tools such as CASBs (Cloud Access Security Brokers), Zero Trust frameworks, and centralized IT management enables companies to detect and control Shadow IT. By taking a proactive stance, organizations can strike the balance between productivity and a secure working environment.
