Every day at our Certified Security Operations Center GmbH, we see how a high-risk situation unfolds—the uncontrolled use of tools that can pose a danger to an entire company. Tools are quickly installed, accounts are created on the fly, and files are uploaded somewhere—often simply because it’s convenient. This is exactly how shadow IT arises. What makes work easier in the short term leads to a lack of oversight, duplicate solutions, and real security risks in the long term. Especially when everyone “just quickly” downloads something or uses a new SaaS service.
Shadow IT rarely arises intentionally; it creeps into everyday life. A team needs a solution fast; official IT is overloaded or too slow, so they search for tools on their own. A SaaS service is set up in minutes, often without coordination, without review, without documentation. What starts as a practical one-off solution spreads: colleagues adopt tools, share access, or store data outside the intended systems. Over time, these individual decisions add up. Different tools for the same purpose, unknown data flows, distributed accounts without central control. This becomes particularly critical when it comes to cybersecurity: unknown tools expand the attack surface unnoticed. Missing updates, weak passwords, or unactivated security mechanisms make it easy for attackers. Security incidents often go undetected for a long time—often until it’s too late.
No one has a complete overview anymore—neither of the applications in use nor of the stored data or access rights. This is how shadow IT arises: not intentionally, but through many small, understandable decisions in everyday life that develop into an uncontrollable overall picture.
Risks
- Security vulnerabilities: Untested tools may contain vulnerabilities or process data without encryption.
- Data loss: Information resides in external systems without backup or recovery plans.
- Compliance violations: Using unauthorized services may violate data protection or company policies.
- Lack of transparency: No one knows exactly which tools are in use or where the data is stored.
- Uncontrolled access: Accounts and permissions are not centrally managed or revoked.
- Duplicate costs: Multiple teams use different tools for the same purpose.
- Dependency on individuals: Knowledge and access rest with individual employees.
- Integration issues: Shadow solutions often do not fit seamlessly into existing systems.
- Reputational risks: Data breaches or violations can damage the trust of customers and partners.
From a cybersecurity perspective, shadow IT gives attackers exactly what they want—complex, poorly secured systems without central control
- Increased attack surface: Every additional, unknown tool is a potential entry point for attackers.
- Unpatched vulnerabilities: Unofficial applications are often not updated regularly.
- Phishing risks: Employees register for tools using company email addresses, making them perfect targets for targeted attacks.
- Weak passwords: The same or weak passwords are reused multiple times.
- Lack of monitoring: Security incidents in shadow IT tools often go completely undetected.
- Data leakage: Sensitive information ends up in external SaaS services without adequate protection.
- Account takeovers: The lack of multi-factor authentication makes it easier for hackers to gain access.
- Uncontrolled interfaces: API connections to other tools can open up further security gaps.
Our tips
- Establish clear tool approval processes: New SaaS services should be reviewed by IT/Security before use.
- Provide centralized tool catalogs: Employees should know which applications are officially permitted.
- Offer easily accessible alternatives: When legitimate tools are readily available, the urge to use “shadow solutions” decreases.
- Fast IT help desk structures: Short response times prevent employees from seeking solutions on their own.
- Security awareness training: Regularly educate employees about the risks of shadow IT and insecure tools.
- Use SSO and identity management: Centrally manage and control access to tools.
- Implement SaaS monitoring: Identify and assess unknown applications on the network.
- Communicate clear data policies: What can and cannot be stored where.
- Create reporting channels for new tools: A simple process for securely requesting new software instead of using it secretly.
- Foster a culture of openness: No “blame games,” so employees report new tools early on instead of hiding them.
Conclusion
Shadow IT is neither a marginal issue nor an exception—it happens every day, right in the midst of daily work. Usually not due to negligence, but out of a desire to solve things faster and more easily. But that is precisely where the real challenge lies: What feels like productivity at first glance can become a serious security and control issue behind the scenes. The difference isn’t created by bans, but by awareness, transparency, and the right framework conditions. When security and daily work don’t work against each other but function together, a risk becomes a manageable part of collaboration once again.
