Best approaches for malware scanning in Outsystems application
Question

Service Studio Version
11.55.32 (Build 64283)

Hi Community,

We are looking for ways to implement malware scanning for files uploaded in OutSystems applications. Our goal is to ensure that uploaded content is handled securely and meets good security practices. 

Currently we are exploring the use of the VirusTotal API for malware scanning. At the same time, we would like to know about alternative approaches or integrations available that can provide better security. 

Could you please suggest:

  • Other recommended solutions, components, or integrations for malware/virus scanning in OutSystems. 
  • Best practices for securely handling uploaded files in enterprise applications

Would appreciate your suggestions and experiences on this.

Hi @Mohammad Iqbal Yusuf Sheikh ,

Using the VirusTotal API is a good option, but you could also look at other integrations like ClamAV (open-source antivirus) or commercial services such as Symantec, McAfee, or Microsoft Defender APIs. Some teams also use cloud providers (AWS, Azure, GCP) that offer built-in malware scanning services which can be connected to OutSystems via REST APIs.

As for best practices:

  • Always scan files before storing or processing them.
  • Keep files in a quarantined temporary location until verified.
  • Enforce file type and size restrictions (only allow what’s really needed).

It’s often best to combine scanning with good validation and storage practices – that way security isn’t just dependent on a single tool.

Hope this helps!

regards,

Manish Jawla
