ProLion Partner
We deploy ProLion to protect file shares at the storage layer, detecting ransomware behaviour, controlling access automatically, and giving you visibility of who is touching your data and how.
Ransomware on a file share spreads faster than most teams can react.
Most ransomware defence focuses on the endpoint and the network perimeter — stopping the initial phishing email or malicious download. That matters, but it assumes prevention will always work, and it never does completely. Once an attacker has a foothold on a single device with access to a shared drive, mass encryption of thousands of files can begin within minutes, often out of hours when nobody is watching.
We've seen this play out at organisations with otherwise reasonable security — a compromised laptop belonging to a single user encrypts a shared document management system overnight, and the first anyone knows is staff arriving the next morning to find case files or patient records unreadable. By that point the damage is already done and recovery means restoring from backup, with the associated downtime and disruption.
The problem is one of speed and visibility. Traditional file server monitoring, if it exists at all, is usually built for capacity planning and audit logging rather than real-time behavioural detection. Nobody is watching for the specific pattern of a ransomware attack — thousands of rapid renames and encryptions in a short window — until it's already finished.
For organisations handling particularly sensitive shared data — patient records, case files, engineering drawings, financial documents — a storage-level ransomware event isn't just downtime. It's a data breach with regulatory notification obligations, client trust implications and, in healthcare and legal settings, real professional consequences.
- Ransomware encrypting shared drives faster than staff can notice
- File server monitoring built for audit, not real-time detection
- Recovery relying entirely on backup restoration after the fact
- Regulatory and client trust exposure when sensitive shared data is hit
We put behavioural monitoring and automatic containment on the data itself.
We start by mapping your file-share environment — which storage platforms host what data, who has access, and which shares carry the most sensitive or business-critical content. This tells us where monitoring and automatic containment deliver the most value first, rather than deploying evenly across everything regardless of risk.
ProLion is then configured to watch file access patterns directly at the storage layer, looking for the specific signatures of ransomware behaviour — abnormally fast mass encryption, bulk renaming, or unusual deletion rates from a single account or device. When that pattern is detected, access can be cut automatically within seconds, containing the attack to a handful of files rather than an entire share.
Alongside detection, we set up data access monitoring so you have an ongoing record of who is accessing what, which is valuable well beyond ransomware scenarios — insider risk, accidental bulk deletion, and audit requirements from clients or regulators all benefit from the same visibility.
This sits alongside your existing endpoint protection, network security and backup strategy rather than replacing any of it. We're specific about where it fits: it's the layer that limits how much damage happens between initial compromise and containment, which is the window where most of the real cost of a ransomware incident is created.
- File-share risk mapping before any deployment decision
- Behavioural detection tuned to genuine ransomware patterns, not false positives
- Automatic access containment within seconds of detection

Built for organisations that need the work done properly.
Healthcare providers and NHS suppliers
Organisations holding patient records on shared storage where a ransomware event carries regulatory and clinical consequences.
Legal firms with document management systems
Firms where case files sit on shared drives and downtime or data loss directly affects client service and confidentiality.
Manufacturers with shared engineering data
Businesses whose ERP or design data on shared storage would be costly to lose or have encrypted mid-production.
Organisations that have experienced a near-miss
Businesses that caught an attempted ransomware attack on a file share and want structural containment in place, not just faster backup recovery.
What changes once the work is done.
What changes once storage-level ransomware protection is in place.
Attacks contained in seconds, not hours
Automatic access cut-off limits ransomware encryption to a small subset of files rather than an entire share.
Reduced reliance on backup as the only defence
Backups remain the safety net, but far less recovery is needed because the attack is contained early.
Clear data access audit trail
Ongoing visibility of file access supports regulatory evidence requests and internal investigations.
Lower regulatory and breach notification exposure
Smaller-scale incidents are less likely to trigger full data breach notification obligations.
Cyber resilience evidenced, not assumed
A documented control that insurers and clients increasingly ask about directly for shared data protection.
Confidence for regulated data holders
Healthcare and legal organisations can demonstrate a specific control protecting the data that matters most to their clients.
Why we treat storage-level protection as a distinct layer, not an add-on.
It's easy to assume backup and endpoint protection together are enough. In practice, the gap between initial compromise and detection is where most of the real damage in a ransomware incident happens, and that gap sits at the file-share level far more often than security teams expect. Storage-level monitoring closes that specific gap rather than duplicating what other controls already do.
Our role is to make sure ProLion is deployed against the shares that actually matter, tuned to your genuine usage patterns so it doesn't generate noise, and integrated with the incident response process you already have — rather than becoming a separate alert stream nobody checks.
We work with organisations across Chesterfield, Sheffield, Derby, Nottingham, Leeds, Manchester, Birmingham and London, with healthcare and legal clients in particular asking for this level of control as ransomware targeting shared clinical and case data has become more common. The underlying deployment work is consistent regardless of sector.
This is a technology integration we provide, not a claimed partner tier or certification on ProLion's behalf — we describe capability honestly, based on what we've deployed and tested, rather than asserting a formal designation we can't verify.
Questions we are asked most often.
What does ProLion actually protect against?
ProLion focuses on ransomware behaviour at the storage layer — detecting the rapid file encryption and mass-rename patterns that ransomware produces on file shares, and cutting off access automatically before an attack spreads across the whole estate. It works alongside endpoint and network security rather than replacing either.
Does this require replacing our existing storage or NAS?
No. ProLion is designed to sit alongside common enterprise storage platforms and file-share environments rather than requiring a hardware refresh. We assess your current storage estate first and confirm compatibility before recommending any deployment.
How is storage-level protection different from endpoint antivirus?
Endpoint tools look at what's happening on individual devices. Storage-level monitoring looks at what's happening to the shared files themselves — an infected laptop that starts encrypting thousands of files on a shared drive within seconds is a pattern storage monitoring catches directly, sometimes before endpoint tools flag the source device at all.
Will this slow down normal file access for staff?
Configured correctly, no. Monitoring runs against file access patterns in the background, and access controls only trigger when behaviour genuinely looks like an attack — mass encryption, mass deletion or bulk renaming at a rate no ordinary user activity produces. Normal day-to-day file use is unaffected.
Who typically needs this level of storage protection?
Organisations holding large volumes of sensitive shared data where a ransomware event on a file share would be severe — healthcare providers, legal firms with document management systems, and manufacturers with shared engineering or ERP data. It's a targeted control, not something every small business needs by default.
How does this fit with our existing backup strategy?
Backups remain essential and this doesn't replace them. What storage-level protection changes is how much damage happens before backups are needed at all — cutting off an attack within seconds rather than discovering the scale of encryption only once recovery from backup begins.
