What is Shadow IT and what risks does it pose for businesses?

Within your company’s corridors, your employees are probably using dozens of applications that your IT department doesn’t even know about. This phenomenon, known as Shadow IT, is quietly reshaping the technological landscape of organizations. Far from being anecdotal, this “ghost IT” now represents one of the major challenges for corporate security.

Shadow IT: when efficiency goes hand in hand with secrecy

Imaginez cette situation : votre équipe commerciale utilise une application de messagerie gratuite Imagine this situation: your sales team uses a free messaging app to coordinate their activities, while the marketing department stores its visuals on a personal cloud. These ghost IT practices are what we call Shadow IT – the use of tools and software without the approval of the IT department.

This parallel IT does not stem from malicious intent. On the contrary, it often reflects employees’ desire to work more efficiently and optimize their daily tasks. The problem? These solutions completely escape the usual security controls of the IT team and significantly weaken the organization.

The rise of Cloud services and the widespread adoption of SaaS applications have greatly facilitated these shadow practices. Today, just a few clicks are enough to sign up for a collaborative platform or install a file-sharing tool. This ease of access, combined with tools perceived as restrictive or cumbersome, naturally drives users toward unauthorized alternatives.

When the invisible becomes dangerous

Shadow IT practices expose companies to multiple risks, often underestimated by users themselves. The first threat is IT security vulnerabilities. These uncontrolled applications are not monitored by the IT department and can serve as entry points for cybercriminals.

In the healthcare sector, for example, sharing patient records via personal messaging apps can compromise the protection of sensitive health data. For financial companies, using non-compliant tools to process banking information represents a major regulatory risk and may lead to significant financial penalties.

Data leaks are another critical danger of ghost IT. When a salesperson stores presentations on a personal Cloud service, they potentially expose strategic company information. Worse still, if that employee leaves the organization, access to this data may be permanently lost, creating long-term operational issues.

Shadow IT also creates governance challenges for businesses. Data becomes scattered across multiple platforms, leading to hard-to-manage silos and undermining information consistency throughout the organization.

Detecting the invisible: a possible mission

How can these clandestine shadow practices be identified? The first step is to audit actual usage within the organization. This approach often reveals surprises: the gap between official tools and those truly used by employees can be significant.

Awareness is a key lever in combating ghost IT. Employees need to understand that their search for efficiency, while commendable, can jeopardize the security of the entire company. Regular cybersecurity training helps build accountability across teams.

Establishing a clear policy by the IT department is also essential. This policy should define authorized applications, procedures for requesting new tools, and the consequences of non-compliance with established rules.

Sewan: turning risk into opportunity

To address these challenges, Sewan offers a comprehensive approach to controlling shadow practices without stifling innovation. The Sophia platform can centralize a large part of a company’s Cloud and Telecom services, giving IT teams better visibility over the tools in use.

This solution enables fine-grained access rights management based on customized profiles. Rather than banning tools outright, it helps frame usage by offering secure alternatives that meet employees’ real needs.

In terms of network security, Sewan deploys automated solutions including Cloud-based firewalls and real-time monitoring. This approach detects anomalies related to shadow applications while maintaining smooth legitimate usage and limiting intrusion risks.

Winning strategies to tame Shadow IT

The key to success lies in balancing IT security with business flexibility. High-performing organizations adopt a collaborative approach: instead of imposing drastic restrictions, they listen to employee needs and provide official solutions that meet those expectations.

Implementing a fast evaluation process for new software helps channel requests toward secure solutions. This turns potentially dangerous ghost IT into controlled innovation.

Personalized support also plays a crucial role in this transformation. Sewan experts, for example, help companies identify vulnerabilities related to shadow practices and deploy tailored protections—turning a constraint into a competitive advantage.

The future belongs to those who anticipate

Shadow IT will continue to evolve alongside emerging technologies within companies. Generative artificial intelligence already poses new data protection challenges. Organizations that anticipate these changes and adapt their IT security strategies will turn this constraint into an innovation opportunity.

FAQ: your questions about Shadow IT

What is the difference between Shadow IT and BYOD ?

Shadow practices concern applications and services not authorized by the IT department, while BYOD (Bring Your Own Device) refers to the use of personal devices at work. These two phenomena often overlap: using an unapproved application on a personal smartphone multiplies security risks for the organization.

How can teams be effectively made aware?

Successful awareness combines technical training delivered by the IT team, concrete examples of cyberattacks linked to ghost IT, and the presentation of attractive official alternatives. The focus should be on real business consequences rather than simply banning unauthorized tools.

Can Shadow IT be beneficial?

Absolutely! When properly managed, shadow practices reveal unmet needs within organizations and help guide technological innovation. The challenge is to transform employees’ spontaneous initiatives into improvements of official tools while preserving the organization’s IT security.
