Do you know exactly where your cardholder data lives?
PCI DSS v4.0 requires you to locate and scope all cardholder data across your environment before you can protect it. Most organisations find more than they expected. DISCOVER PCI gives you that picture, fast, accurately, and without disruption.
Risk management for all businesses:
You can't control what you can't see.
When a breach occurs or an audit lands, you need answers fast. Working from assumptions under pressure is exactly where organisations make costly mistakes.
PCI DSS v4.0 scoping starts with a question most organisations cannot answer with confidence: where does cardholder data actually live across your environment? PAN numbers, CVV data, and other payment card information spread across endpoints, email archives, cloud platforms, file shares, and legacy systems, often without anyone’s knowledge.
GuardWare DISCOVER PCI is a lightweight, agentless scanning tool built specifically for this problem. It locates and classifies cardholder data across your entire environment, produces the evidence your QSA needs, and gives your team a prioritised remediation path before the assessment begins.
Three-step workflow
The DISCOVER PCI dashboard, ranked findings across devices, SharePoint, and email with data type, filename, and hit count visible.
Locate
Identifies cardholder data, PAN, CVV, and related PCI-regulated content, across endpoints, email, SharePoint, file shares, cloud platforms, and legacy systems. Scans files, text, and images using rule-based classification.
Investigate
Gain detailed insight into every detection, ownership, sensitivity level, classification status, creation date, email context, and file attributes. Your team knows exactly what they are dealing with and where it sits.
Remediate
When sensitive data is found, DISCOVER PCI gives you the tools to act on it immediately. Classify files to bring them under policy control, delete what should not exist, or move data to the right location. Remediation alerts go directly to information owners so action happens at the source, not weeks later in a security queue.
How DISCOVER PCI works
The DISCOVER dashboard, ranked findings across devices, SharePoint, and email with data type, filename, and hit count visible.
Agentless scanning, fast to deploy, zero disruption
Scans M365 email and SharePoint remotely with no local agent required. Connects securely to Windows and Linux environments via WinRM or SSH. Optional local agents for non-remotable devices and servers. Scans files in place, no data movement required.
Works independently of Microsoft licensing
DISCOVER PCI operates independently of specific Microsoft licence tiers. No dependency on Purview or E5 licensing to locate cardholder data across your M365 environment.
Broad environment and file type coverage
Supports most environments and data types, including scanned documents and images. Covers endpoints, servers, file shares, email archives, cloud platforms, and legacy repositories.
Continuous compliance monitoring
Continuous scanning of new data ensures your cardholder data environment stays current between assessments, not just at the point of a QSA engagement.
Multi-agent parallel processing
Multi-agent setup allows parallel scanning across large environments, significantly accelerating the time to a complete picture.
Automated classification
Automatically enforces classification tags on identified cardholder data, supporting the labelling and handling requirements of PCI DSS v4.0.
Centralised dashboards and exposure reports
Real-time dashboards showing exactly where PAN, CVV, and other regulated data resides, ranked by risk and mapped to the repositories that need attention first.
Decentralised remediation with IT oversight
Data owners receive direct remediation alerts, enabling faster resolution without creating a bottleneck for the security team.
If Microsoft 365 is your primary data environment
DISCOVER PCI provides an agentless method of scanning your SharePoint and M365 environment
Connects directly without requiring local agents or changes to your existing infrastructure. It applies Microsoft Purview labels seamlessly to all identified data, so organisations already using Purview can extend their classification framework without starting over.
Agentless architecture
GuardWare DISCOVER PCI is designed for how security teams actually operate. Fast to deploy, secure by design, and built to work alongside your existing stack – not replace it.
The only vendor delivering data discovery, continuous monitoring, and persistent file encryption in a single integrated platform.
PROTECT is the final layer, data that leaves your environment is worthless to anyone without your keys.
Data-Centric Security suite designed as one operational sequence:
Find and classify
Full monitoring across all channels including M365
Persistent file encryption
Start with a 2-hour scoped data snapshot.
See exactly where your sensitive data lives, no lengthy deployment, no guesswork. The GuardWare DISCOVER PCI Proof of Value is scoped to fit your specific data visibility challenge. We scan the repositories that hold your sensitive data and hand you a ranked exposure report and remediation plan you can act on immediately.
- Scope the repositories that matter most to your organisation
- 2-hour setup, operational with no disruption to your environment
- Receive a ranked exposure report and prioritised remediation plan
Real-Time Visibility for Confident Compliance
"The part that makes breaches expensive isn't the intrusion. It's the uncertainty afterwards, what data was involved, where it lived, and who could reach it. DISCOVER was built to close that gap, fast, without disruption, and without guesswork."
Together, the suite gives you control end to end.
GuardWare’s Data-Centric Security suite is designed as one operational sequence, find, monitor, and protect your sensitive data across its entire lifecycle.
Find and classify
Map sensitive data across all repositories, including M365. Know what you have, where it lives, and what needs to be tightened first.
Full monitoring across all channels
Extends visibility beyond M365 to endpoints, cloud platforms, AI tools, USB activity, web traffic, and home environments. The complete picture, across every channel where data moves.
Encrypt and control
Persistent file encryption so sensitive files remain protected even when they leave your environment, with remote key revocation for every file, including files already shared externally.
