Continuous Session Governance for MSSPs

Govern every privileged session. Protect every customer. Prove it to every auditor.

Keystrike is a continuous remote access governance platform that closes the Governance Gap in MSSP environments. Your MFA confirms identity. Your PAM vaults credentials. Neither governs what happens once the session is active. Keystrike validates every privileged remote action in real time through cryptographic attestation of verified physical human input — blocking unauthorised commands before they execute and producing tamper-evident audit records for every session across every managed environment.

MSSPs Face a Governance Gap No Perimeter Tool Can Close

Your admin credentials are the most valuable target in your customers' environments — and the hardest to defend with conventional tools.

MSSP Accounts as Primary Attack Targets

A single compromised MSSP admin credential provides attackers with privileged access across every environment your team manages. MFA confirms the login — it cannot verify what happens inside the session once access is granted. In 2022, the Five Eyes intelligence alliance — comprising CISA, the NCSC, the FBI, and security agencies from Australia, Canada, and New Zealand — issued a joint advisory specifically warning that MSSPs are primary targets for state-sponsored actors and ransomware groups seeking simultaneous access to multiple downstream customer environments.

  • • Admin session verification at the keystroke level
  • • Credential theft and session hijacking prevention
  • • Post-authentication enforcement across all managed environments

Cross-Customer Contamination

Attackers who compromise one MSSP session can move laterally across customer environment boundaries — propagating ransomware, exfiltrating data, and establishing persistence across multiple customers before any alert fires. Keystrike blocks lateral movement at the command level before it crosses the customer boundary.

  • • Environment boundary enforcement
  • • Lateral movement prevention
  • • Blast radius containment

Proving Access Integrity to Customers

Customers increasingly demand cryptographic proof that their MSSP cannot be impersonated. Keystrike produces tamper-evident session records for every privileged action — giving you the evidence to demonstrate accountability at every level and a differentiated service tier to go with it.

  • • Tamper-evident audit trails for every privileged session
  • • Compliance-ready records for NIS2, ISO 27001, and SOC 2
  • • Competitive service differentiation

WHERE EXISTING CONTROLS FALL SHORT

Three Attack Paths That Bypass MFA, PAM, and EDR in MSSP Environments

Session Hijacking and Admin Credential Abuse

Attackers who compromise an MSSP workstation operate inside a legitimate session — invisible to MFA, PAM, and post-authentication controls. Every command appears authorised. Every action looks like the engineer. By the time the breach is confirmed, customer environments across the managed portfolio are already compromised.

Keystrike's continuous session governance closes this gap by continuously validating that every command originates from verified physical input on an approved device — not just at login, but throughout the entire session. The moment that changes, Keystrike acts: blocking the command, isolating the workstation, and triggering automated response before damage spreads.

Incident: The 2021 Kaseya VSA ransomware attack exploited MSP remote access tools to deploy REvil ransomware across approximately 1,500 downstream businesses in 17 countries — all through legitimate remote sessions. Keystrike would have blocked the unauthorised remote commands before execution — containing the blast radius regardless of credential validity.

Cross-Customer Lateral Movement

Once inside an MSSP session, attackers can pivot across customer environment boundaries — using the same credentials, the same tools, and the same access that MSSP engineers use legitimately every day. Network segmentation and perimeter controls offer no defence against an authenticated session that already has permission to cross boundaries.

Keystrike closes this gap by validating every command that crosses environment boundaries, blocking RDP hijacks, inherited sessions, and credential replay before lateral movement can propagate to downstream customers.

Incident: In the SolarWinds SUNBURST attack (2020), attackers used compromised supply chain access to move laterally through 18,000+ organisations — many through MSP and managed service channels. The breach remained undetected for nine months. Keystrike limits attacker dwell time to minutes — not months.

Supply Chain and Remote Tool Exploitation

MSSP operations depend on remote management tools — RMM (Remote Monitoring and Management) platforms, SSH jump servers, RDP gateways, and scripting frameworks. Attackers increasingly target these tools directly, exploiting vulnerabilities or stolen credentials to push malicious commands across entire customer portfolios simultaneously — far faster than any human response can contain.

Keystrike closes this gap by requiring every command to be cryptographically attested to physical human input. Automated scripts, injected commands, and remote tool exploitation generate no valid attestation — and are blocked before execution.

Incident: The ConnectWise ScreenConnect vulnerability (February 2024) was exploited within 48 hours of disclosure, allowing attackers to push ransomware across MSP customer environments through legitimate remote access tools. With Keystrike, commands from unattested sources are blocked regardless of the delivery mechanism.
POST-AUTHENTICATION SECURITY GAP

Why MFA, PAM, and SIEM Cannot Secure Privileged Sessions in MSSP Environments

Security ToolWhat It ProtectsPost-Authentication Gap
Firewalls / VPN / MFAPerimeter and identity at loginSession activity after access is granted
PAM — Privileged Access Management (e.g., CyberArk, BeyondTrust)Credential vaulting and access controlsSession activity after the vault is opened
SIEM — Security Information and Event Management (e.g., Splunk, Microsoft Sentinel)Centralised alerts and compliance reportingReactive — alerts after damage is done
EDR — Endpoint Detection and Response (e.g., CrowdStrike, Microsoft Defender)Malware detection and endpoint telemetryBlind to valid credential theft and session misuse
Keystrike — Privileged Session GovernanceEvery command in every privileged sessionNone. Unauthorised commands blocked before execution.

Keystrike does not record keystrokes, credentials, or personally identifiable information. Session verification is cryptographic — not behavioural — eliminating false positives and analyst alert fatigue.

COMPLETING YOUR SECURITY STACK

IAM and PAM grant access. SIEM and XDR log events after the fact. Keystrike governs the live session.

You don't have to rip out or replace your existing stack. Keystrike is the essential final piece that makes your existing MFA, PAM, and SIEM infrastructure deliver Continuous Access Governance — closing the Governance Gap inside every privileged session across your entire managed portfolio.

COMPLIANCE AND GOVERNANCE

Continuous Session Governance for NIS2, DORA, ISO 27001, and SOC 2 Requirements

Every privileged session produces continuous, tamper-evident audit records that satisfy MSSP regulatory and contractual requirements as a direct output of governance — not as a separate compliance process.

CONTROL — Real-Time Enforcement

Workstation Agent

A lightweight agent on the MSSP engineer's device recognises legitimate physical keystrokes and mouse clicks across every managed customer session, and submits cryptographic attestations confirming their legitimacy to the central Keystrike service.

2
CONTROL — Deterministic Blocking

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.

3
SEE — Complete Session Visibility

Live Visibility

The Keystrike SEE module maps all remote protocols across every managed environment — RDP, SSH, PowerShell Remoting, WinRM, WMI, SMB, and more — surfacing which sessions are governed and where policy gaps remain across your entire customer portfolio.

Frequently Asked Questions About MSSP Session Governance

How does Keystrike prevent cross-customer contamination?

Keystrike validates every command that traverses customer environment boundaries using cryptographic attestation of physical human input. It blocks session inheritance, credential replay, and RDP hijacks before lateral movement can propagate to downstream customers — at the command level, not the network level.

Does Keystrike replace our existing PAM or SIEM?

No. Keystrike completes your existing security stack — it does not replace any component. PAM continues to vault credentials and control checkout. SIEM continues to aggregate logs and generate alerts. Keystrike adds the missing layer: continuous governance inside the live privileged session. It deploys alongside your existing infrastructure in approximately 20 minutes per environment.

What is the Governance Gap in MSSP environments?

The Governance Gap is the unprotected space between when a user is authenticated and what they actually do inside the session. In MSSP environments — where a single admin session can reach every customer environment — this gap is the attack surface that credential theft, session hijacking, and cross-customer lateral movement exploit. Keystrike closes the Governance Gap by governing every command inside the live session in real time.

How long does Keystrike take to deploy across managed environments?

Keystrike deploys in approximately 20 minutes per managed environment. No lengthy professional services engagement, no complex integration project. It integrates with existing MFA, PAM, and SIEM infrastructure with no rip-and-replace.

Does Keystrike record or store keystrokes?

No. Keystrike verifies that commands originate from a physical human operator through cryptographic attestation — without recording keystrokes, capturing screens, or conducting behavioural analysis. Session verification is deterministic, not probabilistic.

What compliance frameworks does Keystrike support for MSSPs?

Keystrike maps directly to NIS2, DORA, ISO 27001:2022, SOC 2 Type 2, NIST Cybersecurity Framework, Cyber Essentials, and applicable data protection regulations — through continuous session governance, cryptographic attestation, and tamper-evident audit records for every privileged session across every managed environment.

Can Keystrike be offered as a managed service to MSSP customers?

Yes. Keystrike provides MSSPs with a differentiated service tier — offering customers cryptographic proof that every privileged session in their environment is governed, verified, and audit-ready. The tamper-evident session records become a competitive differentiator for customer retention and new business.
