File Upload Security
Protect File Uploads
Cyberthreat actors are constantly improving their tactics to evade file upload attack protections. Complete file upload security requires a comprehensive approach that utilizes Deep CDR, multiple anti-malware engines, data loss prevention, vulnerability detection, threat intelligence, and next-gen sandbox analysis.
Is Your Web Application Secure?
Attackers and malicious insiders utilize a variety of techniques including malware, zero-day attacks, and exploitable vulnerabilities, to gain unauthorized access to your organization's systems and data.
40%-80%
of malware and viruses go undetected by a single antivirus engine.
88%
of malware employs techniques to evade sandbox detection
66%
of all malware evaded signature-based protection
File Upload Security Challenges
To address the challenge of file upload security, traditional methods such as single engine antivirus software, web application firewalls (WAF), firewalls, and sandboxing require additional layers of protection.
OPSWAT provides innovative solutions that go beyond traditional approaches to ensure comprehensive protection against all forms of file-based threats.
Known Malware
With over one billion types of known malware, ensuring that every file uploaded to your system is malware-free is a significant challenge. Single-engine anti-malware scans only detect 40-80% of known malware, leaving organizations vulnerable to data breaches.
Targeted Attacks
Cybercriminals can use custom-crafted malware to exploit zero-day vulnerabilities for targeted attacks on file upload capabilities in web applications. Traditional solutions like web application firewalls and single engine antivirus engines are ineffective against zero-day threats.
Sensitive & Unwanted Data
Enabling file upload capabilities may pose compliance and regulatory risks, as users could potentially upload personally identifiable information (PII) or other sensitive data that could make you liable if you fail to meet compliance mandates like GDRP and PCI DSS.
Vulnerabilities in Binaries
The challenge of ensuring secure binary files lies in identifying and addressing vulnerabilities and weaknesses. When vulnerabilities are present in binaries uploaded to web applications, attackers may gain unauthorized access to hardware, software, data, or other assets within an organization's network.
Compliance
Organizations may need to select malware engines from vendors that are approved by their government and meet national security requirements. This ensures that their cybersecurity measures align with government standards and mitigates the risk of using software that may compromise national security.

Frequently Asked
File Upload Security Questions
Different modules process different files. Our Deep CDR module supports over 130 file types.
- Validate file types and sizes to prevent the upload of malicious files or excessively large files that can overwhelm the server.
- Implement input validation to prevent malicious input in file names or metadata.
- Utilize server-side scanning and antivirus software to detect and block any malicious files.
- Enforce access controls and authentication mechanisms to prevent unauthorized access to uploaded files.
- Use encryption to protect the confidentiality of files in transit and at rest.
- Regularly audit and monitor file uploads for any suspicious activity or anomalies.
To ensure secure file upload on a website, validating file types and sizes, utilizing server-side scanning and antivirus software, enforcing access controls and authentication mechanisms, storing uploaded files in a secure storage solution, monitoring software for vulnerabilities, and keeping software up-to-date, and providing user training are all crucial steps.
To secure anonymous file uploads from attacks, website owners can implement measures such as file size limits, file type filters, antivirus software, captchas, session timeout, and sandboxed environments.
