Shadow IT refers to any technology—apps, services, devices, or software—that employees use without explicit approval from the IT department. It often emerges when official tools feel slow or lack needed features, prompting staff to turn to familiar alternatives.
Shadow IT is the use of unauthorized technology within an organization. It happens because employees seek faster, more convenient tools that better fit their workflows, especially in remote or hybrid settings.
Typical examples include personal cloud storage (Google Drive, Dropbox), unofficial project‑management apps (Trello, Asana), messaging platforms (WhatsApp, Slack), and personal devices used for work (BYOD). Even unsanctioned browser extensions or trial software can count as shadow IT.
Unauthorized apps often lack enterprise‑grade security controls, making them easy entry points for malware or phishing attacks. They may use weak passwords, skip multi‑factor authentication, and remain unpatched, exposing the network to threats.
Data stored in unsanctioned services can bypass compliance checks, jeopardizing regulations such as GDPR, HIPAA, or CCPA. Without centralized oversight, it’s nearly impossible to prove that data handling meets legal standards.
Teams often purchase duplicate subscriptions or pay for individual licenses instead of leveraging volume discounts. Untracked services can also incur unexpected storage or premium feature fees, inflating the IT budget.
IT cannot protect what it cannot see. Lack of visibility creates blind spots, making it difficult to enforce backups, disaster‑recovery plans, or monitor data flows across the organization.
Start with network monitoring to discover unknown traffic, then survey employees about the tools they use daily. Treat the audit as a discovery exercise—not a punishment—to understand real needs.
A concise policy defines what is allowed, outlines the request process for new tools, and states consequences for violations. Communicating it widely ensures everyone knows the rules and the rationale behind them.
Regular training highlights the security and compliance dangers of unsanctioned tools. It also teaches staff how to request approved solutions, turning potential workarounds into formal requests.
Deploy a Cloud Access Security Broker (CASB) to gain visibility into all cloud usage, enforce data‑security policies, and block risky services in real time.
Implement a BYOD policy that mandates security controls such as device encryption, mobile‑device‑management (MDM), and strong authentication before corporate data can be accessed.
Palisade’s email security platform scans your outbound traffic to identify all sending services, even those set up without IT’s knowledge. By authenticating every email, it stops phishing attacks and reveals hidden email‑sending tools.
Check your email security score to see how well your organization is protected.
A CASB provides a centralized dashboard that lists every cloud app in use, whether approved or not. It lets you enforce encryption, data‑loss‑prevention, and access policies across all services.
A sandbox lets teams trial new software under IT supervision, ensuring security controls are applied before full deployment. It encourages innovation while keeping risk in check.
Shadow IT is the use of unsanctioned technology that can create security gaps, compliance violations, hidden costs, and visibility problems. Mitigate it by auditing tools, establishing clear policies, improving official solutions, training staff, and using tools like CASBs and Palisade’s email security to gain control.
Start with network traffic analysis, use a CASB, and survey employees about the apps they rely on daily. Combine automated discovery with direct feedback to build a complete inventory.
Unpatched software, weak authentication, and lack of encryption can expose your network to malware, phishing, and data exfiltration. Unauthorized email services also increase phishing risk.
Yes. Data stored in unsanctioned clouds may not meet GDPR, HIPAA, or CCPA requirements, making it difficult to prove compliance during audits.
Define allowed tools, outline a simple request workflow, set approval criteria, and communicate the policy widely. Include consequences for violations and regularly review the policy.
Palisade monitors all outbound email traffic, flags unknown sending services, and enforces DMARC to protect your domain. This visibility helps you discover hidden email tools and stop phishing attacks.
