Your file shares are the
ransomware highway. Close it.
Standard CIFS/SMB was never built for Zero Trust - it's flat, over-trusting, and the number-one path ransomware uses to spread across file shares. truePass Guard replaces it with a hardened tunnel over port 443, TLS 1.2/1.3 - MFA on every file action, CDR sanitization on every file, and all shares hidden - without changing how your users work.
Why it works.
Three ways your file shares become a breach.
The protocol most organizations rely on for files was designed for a trusted LAN - not for today's threat landscape.
Ransomware spreads share to share
Standard CIFS/SMB is flat and over-trusting. Once ransomware reaches one endpoint, it enumerates and encrypts every reachable share - turning a single infection into an enterprise-wide outage. File shares are the number-one propagation path.
No identity, no per-file control
Traditional shares authenticate at the mount, then trust every action underneath. There's no MFA per file, no content inspection, and no way to stop a compromised account from copying, encrypting, or exfiltrating sensitive files at will.
Exposed protocol, exposed servers
SMB ports, relay attacks, and visible file servers give attackers a rich target surface. Your real storage names and network addresses are discoverable - and every unpatched SMB CVE becomes a direct route to your data.
A flat file share is not Zero Trust. It authenticates once and trusts everything after. Zero Trust means every file action is verified against identity, every file is inspected before it lands, and the shares themselves stay hidden - so a compromised endpoint can't turn your storage into a ransomware target.
Same file shares.
Hardened protocol underneath.
truePass Guard replaces standard CIFS/SMB with a hardened tunnel over port 443, TLS 1.2/1.3 - with no change to how your users work. They keep mapping the same drives and opening the same files; underneath, every session is encrypted end to end, MFA is enforced on each file action, and CDR sanitizes every file before it enters the network.
Users connect to a single virtual namespace, so real server names, addresses, and storage structure stay hidden - all shares invisible to anyone unauthorized. SMB Signing blocks relay attacks, anomaly detection flags mass-encryption behavior in real time, and every action lands in one unified audit trail. Works across Windows and Linux/Samba file environments.
From identity check to audited session.
Identity & MFA per action
The user authenticates with AD and MFA. Every file action - open, copy, write, delete - is re-checked against identity and policy, not just the initial mount.
Hardened 443 TLS tunnel
CIFS/SMB traffic is carried over port 443, TLS 1.2/1.3, with SMB Signing. No exposed SMB ports, no relay attacks, real storage stays hidden behind a virtual namespace.
CDR on every file
Files are sanitized through Content Disarm & Reconstruction before they enter the network - stripping embedded threats so malware never reaches your shares.
Anomaly detection & audit
Mass-encryption and abnormal access patterns are flagged in real time. Every action is logged in one audit trail, exported to Syslog, SIEM, and SOC.
Three modules. One unified deployment.
Secure file transfer is enforced through truePass Guard, with Grid and Gravity protecting the servers behind it and the boundaries files have to cross.
Hardened CIFS/SMB over TLS 443 - shares stay hidden from enumeration, every access is authorized per identity, and inbound files are sanitized before they land.
Isolates file servers in their own zone, so ransomware that lands elsewhere on the network can never reach them laterally.
Moves files across the separation line into isolated and air-gapped zones, replacing the USB drive carried by hand.
Real file environments. Real protection.
These are the file environments where teams have replaced exposed SMB with truePass Guard.
Departments keep mapping the same network drives - finance, HR, legal - but every session now runs over 443 TLS with MFA per file and CDR. Ransomware that lands on one endpoint can't enumerate or encrypt the shares, because they're hidden and every action is verified.
Guard secures CIFS/SMB across heterogeneous environments - Windows file servers and Linux/Samba alike - under one policy. No need to rip and replace storage; the hardened protocol sits in front of what you already run.
Patient records, financial documents, and classified files need encryption in transit and at rest, MFA per file, and a tamper-proof audit trail. Guard delivers all three on the shares themselves - so compliance is enforced where the data actually lives.
Documents arriving from vendors, email, or removable media pass through CDR sanitization before they reach a share - embedded macros, exploits, and hidden payloads stripped out. Malware never gets a foothold on your file servers.
What changes when you make the shift.
Ransomware contained
Hidden shares + anomaly detection stop mass-encryption cold.
Encrypted end to end
CIFS/SMB over 443 TLS, in transit and at rest.
MFA per file action
Every open, copy, and write re-verified against identity.
CDR on every file
Embedded threats stripped before files reach a share.
No client changes
Users keep the same drives and workflows. Zero retraining.
Audit-ready compliance
Every file action logged. GDPR, HIPAA, PCI-DSS, ISO 27001.
