Introducing Anvil, the firewall for your folders! Anvil provides ransomware, malware and intrusion detection technology designed to keep files safe using rule-based folder access.

Ransomware, malware, and other APT’s (advanced persistent threats) are rapidly becoming a significant issue, with attacks increasing in sophistication and frequency, and, with 1.5 million new phishing sites created every month (source: along with phishing emails, the threat to personal and professional files has never been more significant.

Anvil changes the way we look at file protection, by providing a clever rules-based engine that gives you full control over access to any folder on your system.

“In my opinion, this is the biggest concern that exists now is the threat from software that encrypts” – Steve Gibson, Gibson Research, Security Now podcast, episode 696

There is an old saying… “prevention is better than a cure”. Anvil stands alone when it comes to explicit file protection.
Here are some important facts we pulled from our Why Anvil? white paper

Anti-virus solutions are not engineered to protect files
Many third-party anti-virus solutions do not offer explicitly file protection, or if they do, its an afterthought, and it's often not clear how the protection works. Anti-virus mostly relies on process filtering, to catch malware as it attacks or infects your system.

Backups can give a false sense of security
While we highly recommend users back up their systems, backups are a double-edged sword, in that you may end up merely backing up the very encrypted files you are trying to protect yourself against.

Windows 10 offers no real protection
If you have Windows 10, with Controlled Folder Access enabled, you're protected, right? Well, you would've thought so. However, Windows Controlled Folder Access can be disabled or modified by any application that obtains elevated rights! Now, given the number of zero-days, phishing attacks and other threats, gaining elevated rights is not as difficult as you would have thought. Not to mention you are relying on Windows Defender to determine who are the good and bad actors, and, if Windows were able to do this reliably, you wouldn’t be reading this!

Anvil's cloud-based security
To ensure security, Anvil uses cloud-based authentication, ensuring that, no matter how compromised a system becomes, rule modification is not possible.

Anvil, engineered for a modern file system
Anvil is the only platform available specifically engineered to protect, monitor and add features to file system folders, including network endpoints. From monitoring and access control, through to intrusion detection and immutable folders, Anvil provides robust binary protection.


Having precise control over what applications can access a folder, is the only way you can be sure your files are truly protected.


Network endpoints are often the first targets for malicious processes, limit access to network endpoints to ensure backups and/or shared files remain protected.


Anvil provides real-time, autonomous protection without the need to downloading threat signatures, or performing web-based analyses.


Digitally signed applications are no longer safe, as malware is increasingly being found to have been digitally signed by valid and credible certificates.


Create a “vault style” folder that contains files that, once written, can no longer be altered, thus providing a safe place for archived files.


Place files on your system that, when access (read or written to), will send a silent alert to the specified email addresses.


Keep contents of a file safe with encryption that only you can access. All files encrypted are done so using a TNO (trust no one) encryption model.*


Simply, clean and state of the art web-based interface, ensures easy configuration on your local, networked and enterprise machines.**

* File encryption arrives in v1.3. ** Network/enterprise support arrives v1.4

When it comes to security, it's essential to know with whom you are trusting your data. Division-M has a long history working with file systems, from hard drives through to spinning media, we've tackled many tough challenges.

Division-M is a software engineering company based in Sydney, Australia. We specialize in client/server applications and device driver development for the Microsoft Windows platform. Division-M was formed as a division of Jacal Consulting in 2003 (hence the name), and become a stand-alone entity in 2010.

Division-M has been responsible for many successful products including Game Jackal (acquire by SlySoft Inc. in 2007), Drive Bender and Cloud Xtender. In all, we have sold hundreds of thousands of licenses across the global, over many years.

Anvil File Security came to life as a product while we were working on Drive Bender v3.0, as it contains similar technology. Moreover, we are looking to create a file system platform that will allow us to bolt on all sorts of great technology, from file-based events that can trigger custom actions through to real-time file duplication and cloud file syncing.
