Govern Every Workforce Session. Protect Every Patient.
Keystrike is a continuous remote access governance platform. It governs what happens after access is granted — providing live visibility into every remote session, blocking unauthorised commands before they execute through deterministic enforcement, and generating continuous audit-ready proof of control. Built for healthcare environments where every remote session carries operational and patient safety risk.
Keystrike does not record keystrokes, credentials, or personally identifiable information. Session verification is cryptographic — not behavioural — eliminating false positives and privacy exposure.
The Governance Gap Healthcare Cannot Ignore
70%
of healthcare breaches involved compromised credentials
Verizon DBIR 2024, Healthcare subset
Healthcare organisations have invested heavily in MFA, IAM, PAM, SIEM, and EDR. These tools do their jobs. MFA validates identity at login. PAM controls who can start a privileged session. SIEM collects and stores event logs.
But once a session begins, those tools stop governing it.
There is a persistent Governance Gap between access intent — who you authorised — and access reality — what actually happens inside the session. That gap is where ransomware deploys, where credentials get abused, and where lateral movement unfolds. It is where no tool in your current stack operates.
Keystrike closes that gap.
Healthcare Faces a Security Gap No Perimeter Tool Can Close
Attackers don't break in. They operate inside legitimate sessions after access is granted.
Ransomware and Operational Shutdown
A single compromised session can encrypt EHRs, pharmacy systems, billing infrastructure, and imaging simultaneously — disrupting care before any alert fires. HIPAA, HITECH, and CMS requirements demand continuous controls, not post-incident logs.
- · EHR and clinical system protection
- · Blocks ransomware deployment commands inside active sessions
- · Operational continuity during active threats
Third-Party and Vendor Access
Healthcare organisations depend on a broad ecosystem of vendors, labs, and service providers — every external connection via VPN, RDP, or remote management tools is a potential entry point. Keystrike governs every vendor session without disrupting clinical workflows.
- · Vendor session governance
- · PHI exchange verification
- · Blocks commands from compromised vendor sessions
Medical Device and Lateral Movement
Attackers who compromise a workforce session can pivot into imaging, pharmacy, and infusion pump networks — even with segmentation in place. Keystrike validates every session crossing into device networks, blocking lateral movement at the command level.
- · Device network boundary enforcement
- · Lateral movement containment
- · Patient safety continuity
Three Attack Paths That Bypass MFA, IAM, and EDR in Healthcare Environments
Ransomware Deployed Through Legitimate Sessions
Modern ransomware attacks don't breach the perimeter — they unfold inside authenticated sessions. Once inside, attackers encrypt EHRs, pharmacy dispensers, billing systems, and imaging platforms simultaneously. By the time detection tools fire, critical clinical operations are already offline.
Keystrike closes this gap by continuously verifying that every command inside the session originates from verified physical input on an authorised device — interrupting ransomware deployment commands and blocking lateral spread before they reach clinical systems.
Incident: The 2024 Change Healthcare ransomware attack disrupted billing, pharmacy, and EHR systems across the U.S. — 74% of hospitals reported direct patient care impact and 94% experienced financial consequences. Keystrike would have stopped the impact by blocking unauthorised remote commands mid-session before systems were encrypted.
Third-Party Vendor Compromise and PHI Exfiltration
Healthcare organisations depend on external vendors, labs, transcription services, and claims processors that connect via VPN, RDP, SSH, and remote management tools. Weak credentials, outdated endpoints, or inherited sessions create direct pathways to protected health information and internal infrastructure.
Keystrike closes this gap by requiring every remote action to be tied to verified physical input from an authorised device — preventing attackers from using stolen credentials, inherited sessions, or compromised vendor access to reach PHI.
Incident: The 2025 Yale New Haven Health breach exposed 5.56 million patient records through compromised third-party access to secondary servers. Keystrike would have stopped the impact — session-level enforcement ensures only verified human actions can execute, blocking misuse of vendor sessions regardless of credential validity.
Lateral Movement into Medical Device Networks
MRI machines, infusion pumps, pharmacy dispensers, and imaging systems often run legacy operating systems and remain connected to clinical networks. Attackers who compromise a single workforce session can pivot into these device networks — even through segmented environments — putting patient safety at direct risk.
Keystrike closes this gap by validating every workforce session crossing network segment boundaries, blocking credential replay, RDP hijacks, and inherited sessions before lateral movement can reach connected medical devices.
Incident: The 2025 Frederick Health breach exposed approximately 934,000 patient records through widespread use of stolen credentials across connected systems. Keystrike would have stopped the impact — continuous session verification prevents attackers from issuing malicious commands even when login credentials are fully compromised.
Why Perimeter Controls Cannot Secure Privileged Sessions in Healthcare Environments
| Security Tool | What It Protects | Post-Authentication Gap |
|---|---|---|
| Firewalls / IDS/IPS / MFA | Perimeter and identity at login | Session activity after access is granted |
| PAM — Privileged Access Management | Who can start a session / vault access | Activity inside the session once it starts |
| SIEM — Security Information and Event Management | Centralised alerts and compliance reporting | Reactive — alerts after damage is done |
| NDR — Network Detection and Response | Network traffic anomalies and lateral movement | Blind to encrypted or legitimate-looking session traffic |
| EDR — Endpoint Detection and Response | Malware detection and endpoint telemetry | Blind to valid credential theft and session misuse |
| Keystrike | Every command in every privileged session | None. Unauthorised commands blocked before execution. |
Keystrike does not replace any of these tools. It completes them — governing the session layer that no other control reaches.
Keystrike does not record keystrokes, credentials, or personally identifiable information. Session verification is cryptographic — not behavioural — eliminating false positives and privacy exposure.
Three Capabilities. One Governance Layer.
Every remote session is visible, enforceable, and provable — from login to logout.
Live Visibility
A live map of every remote session across RDP, SSH, PowerShell Remoting, WinRM, WMI, SMB, TeamViewer, NinjaOne, and more — including unknown connections and unmanaged pathways that no other tool surfaces.
One map replaces raw, noisy logs with live intelligence.
Deterministic Enforcement
Every command inside every session must be tied to verified physical human input via cryptographic attestation. Commands without attestation are blocked before execution. No behavioural scoring. No false positives.
We move you from assuming your policies work to knowing they do.
Audit-Ready Governance
Continuous, tamper-evident evidence of every governed session. HIPAA, HITECH, HITRUST, and NIST audit requirements satisfied as a direct output of governance — not assembled after the fact.
We eliminate the Audit Fire Drill.
Keystrike Completes Your Stack. It Does Not Replace It.
Okta, CyberArk, BeyondTrust
Defines who can access which systems and controls session initiation. Once the session starts, their visibility ends.
Splunk, Microsoft Sentinel, CrowdStrike
Stores event records and fires alerts when patterns match threat signatures. Reactive — by the time detection fires, the damage is already done.
Continuous Remote Access Governance
Governs every action inside the session — in real time, from login to logout. Closes the Governance Gap that IAM, PAM, and SIEM were never designed to cover. Does not replace any of them.
You don't need to replace your multi-million dollar stack. Keystrike is the essential final piece that makes your Okta, your CyberArk, and your Splunk work together to deliver Continuous Remote Access Governance.
Continuous Remote Access Governance That Satisfies HIPAA, HITECH, HITRUST, and NIST Requirements
Every privileged session produces continuous, tamper-evident audit records that satisfy healthcare regulatory requirements as a direct output of governance — not as a separate compliance process.
Keystrike supports compliance with HIPAA Security and Privacy Rules, HITECH, NIST Cybersecurity Framework (800-53) and Zero Trust Architecture (800-207), OCR Enforcement Guidance, CMS Requirements, HITRUST CSF, ISO 27799, and applicable state privacy laws — through continuous authentication, policy-driven access controls, and auditable session records for every remote workforce interaction.
Keystrike is a governance platform. With governance working as designed, compliance evidence is produced continuously, not assembled under audit pressure.
Deterministic Session Enforcement — Not Probabilistic Detection
Workstation Agent
A lightweight agent on the user's device recognises legitimate physical keystrokes and mouse clicks, and submits cryptographic attestations confirming their legitimacy to the central Keystrike service.
Server-Side Terminator
A second lightweight agent on the destination server withholds all input until it receives proof of legitimacy. Attested input is processed. Unattested input — from scripts, injected commands, or compromised sessions — is blocked and an alert is generated in real time.
Live Session Map
The Keystrike SEE module maps all remote protocols across your environment — RDP, SSH, PowerShell Remoting, WinRM, WMI, SMB, and more — surfacing which sessions are governed and where policy gaps remain.
Keystrike completes your existing IAM, PAM, and SIEM stack. No rip-and-replace. Deploys in 20 minutes. Clinicians and staff experience no workflow changes.
