Protect Your File Upload Portals with Menlo Security

Secure all web portal uploads and ingest documents completely risk-free.

No Default Blocking or Needless Alerts. Just Safe Files.

Banks, insurance agencies, and countless service providers use upload portals to accept a wide variety of sensitive files and documents uploaded by third-parties. And in order to keep business moving freely, these organizations must quickly ingest these files without the risk of hidden threats that can cripple entire systems and expose customer information. But there’s no telling where these files came from or what threats could be hiding inside.

While other file security "solutions" will outright block files or convert them into PDFs, this leaves employees with safe, yet useless files—which is entirely counterproductive. Meanwhile, manual processes like quarantining only serve to hold up business and cause frustration for both team members and third-parties alike. To ensure safe file uploads without sacrificing usability and speed, enterprises need to proactively sanitize files while simultaneously retaining necessary components like macros and other active content.

At Menlo Security, we use time-tested, AI-trained technology to do just that. You may call it CDR or file sanitization. We call it Positive Selection®.

Menlo Does What Traditional Solutions Can't

The availability of a 24/7 web portal is essential for many organizations, allowing customers and vendors to upload forms, documents, and a variety of file types wherever they are. Yet, while they increase productivity, bulk file ingestion can also expose businesses to hidden malware—whether it's via a simple online portal setup or a custom web application.

For enterprises processing hundreds, if not thousands of files per day, security teams simply cannot keep up without forcing bottlenecks or human error. Meanwhile, some malware can evade sandboxes and AV solutions only recognize known threats, which means zero-days are likely to make their way in. Powered by a combination of next-gen file sanitization, hash check, AV, and sandbox, Menlo File Security gives you the ability to close the gaps left behind by traditional solutions like EDR, DLP, and AV/sandboxing when used on their own.

By taking Menlo's proactive approach to file security, teams don't have to wait for a file to breach the endpoint. Instead, all uploads are made safe as they happen – in just milliseconds – before they ever reach cloud applications or storage.

What makes Menlo File Security different from other file-specific products?
Violet Plus Mark

Unlike detection-based solutions like standalone AV, EDR, and DLPs that scan for suspicious elements and block and/or flatten some malicious files and miss others, Menlo’s technology automatically rebuilds every single file to deliver 100% safe content without the need to detect malicious elements—no blocking, just proactive prevention.

What use cases does Menlo File Security cover?
Violet Plus Mark

Email: Completely secure every email attachment and suspicious URL. 

Web Applications: Sanitize uploaded files via web portal. 

Web Browser: In just milliseconds, user downloads are disarmed and rebuilt. 

Collaboration Tools: User-to-user file sharing is made secure in real-time.

How much latency is created by Menlo's File Security capabilities?
Violet Plus Mark

Content Disarm and Reconstruction happens in real-time, in just milliseconds, leaving the experience completely transparent to end-users. This includes an initial AV scan and hash checking that is near-instantaneous within the CDR process. For sandboxing, the process is as short or as long as the security team deems necessary.

Does Menlo need to be deployed on endpoints and user devices?
Violet Plus Mark

No. Menlo File Security is agentless and integrated via open API depending on the use case. In cases where organizations require on-prem installation, Menlo can accommodate.

Does Menlo work with web isolation tools?
Violet Plus Mark

As an established browser-agnostic security solution, Menlo natively protects customers from malicious web downloads that move beyond the browser.

Can Menlo tell me about the threats that were prevented?
Violet Plus Mark

Absolutely. Our in-depth threat analytics provide teams with the following:

File type and origin – whether the threat came from an email attachment, browser download, API, or cloud collaboration tool.

Type of malicious content removed – including macros, scripts, exploits, and ransomware payloads.

Hashes, file names, and behavioral indicators – identifiers that trace how similar threats evolve or spread.

Recurring campaigns and targeted users – highlighting which departments, users, or workflows are being probed most frequently.

Which types of files is Menlo capable of sanitizing?
Violet Plus Mark

Menlo can sanitize and rebuild over 220 different file types. This includes complex ones like ZIP, archives, and password-protected files.
