Pool-switching attacks
Attackers silently redirect hashrate to their own pools, skimming revenue while uptime metrics look normal.

behind the block.
Defense-grade cybersecurity, purpose-built for Bitcoin and cryptocurrency mining operations. Assess exposure, harden infrastructure, monitor in real time, and respond when seconds matter.
// 01 THE PROBLEM
Your hash rate is a target. We make sure it stays yours.
Generic MSSPs and IT firms aren't built for ASIC fleets, mining pools, or the OT-IT convergence that defines a modern facility. The threat landscape is mining-specific. Your defenses should be too.
THR-02
Rogue ASIC firmware
Tampered firmware exfiltrates hashrate, opens persistent backdoors, or masks unauthorized configurations.
THR-03
Hashrate theft & cryptojacking
Unauthorized compute use that quietly erodes margin — often invisible to standard infrastructure monitoring.
THR-04
Management interface exposure
Unprotected web UIs and admin panels on mining hardware become entry points for full-fleet compromise.
THR-05
Lateral IT-to-OT movement
Attackers pivot from enterprise networks into the ASIC management layer. Generic security stacks miss this entirely.
THR-06
Insider & supply chain attacks
Physical access abuse, contractor misuse, and compromised firmware delivered through the hardware supply chain.
// 02 FOUR PILLARS
Defense-grade security for mining infrastructure.
A complete security program built on four operational pillars — assessed, hardened, monitored, and defended by engineers who understand mining at the silicon level.
01
PILLAR // ASSESS
Assess
Know your exposure before the attacker does.
- Infrastructure Security AuditNetwork architecture, access controls, IT/OT segmentation review.
- ASIC & Firmware Integrity AssessmentHardware-level inspection for tampered firmware and rogue configurations.
- Vulnerability & Penetration TestingActive scanning and exploitation simulation across the perimeter.
- MITRE ATT&CK Gap AnalysisDefenses mapped against ATT&CK with mining-specific coverage gaps.
- Configuration & Hardening ReviewOS, server, and network configs against CIS / NIST benchmarks.

02
PILLAR // HARDEN
Harden
Reduce the attack surface. Close the gaps.
- Server & OS HardeningLinux/Windows hardening, least privilege, patch policy.
- Network Segmentation & Firewall HardeningIsolate mining hardware from management and external exposure.
- Encrypted CommunicationsEnd-to-end channels for management, pool comms, remote access.
- Privileged Access ManagementMFA, SSH key lifecycle, admin policy enforcement.

03
PILLAR // MONITOR
Monitor
Continuous visibility. Real-time threat detection.
- File Integrity MonitoringContinuous monitoring of critical files, configs, and firmware.

- 24/7 SOC-as-a-ServiceHuman analyst triage, escalation, and continuous coverage.
04
PILLAR // RESPOND
Respond
When something happens, speed and expertise are everything.
- Incident Response RetainerPre-contracted IR capacity with guaranteed response SLAs.
- Active Incident ResponseContainment, investigation, recovery — 24/7 for retainer clients.
- Threat HuntingProactive human-led hunts for TTPs that automation misses.
- Digital Forensics & Root CauseFull-chain investigation for insurance and legal use.
- Post-Incident HardeningRemediation sprint to close exploited vectors and prevent recurrence.
- Supporting AdvisoryvCISO retainer, compliance, awareness training, IR documentation.
// 03 WHY HASHSENTINEL
The only security firm purpose-built for mining.

STEP 02
Harden
Implement segmentation, access controls, and ASIC fleet standards to close known gaps.
STEP 03
Monitor
24/7 detection, SIEM correlation, and hashrate integrity monitoring with human triage.
STEP 04
Respond
Pre-contracted IR with guaranteed SLAs, forensics, and post-incident hardening.
// 06 ABOUT
Built by operators. For operators.
HashSentinel is created by security industry professionals with deep operational experience in Bitcoin mining infrastructure. We've stood up SOCs, run incident response for institutional infrastructure, and worked inside mining facilities at every scale — from a few hundred nodes to multi-site, multi-megawatt deployments.
That dual fluency is the point. Generic MSSPs treat mining like any other workload. Traditional IT security firms don't understand ASIC firmware, pool protocols, or the operational tempo of a 24/7 hashing facility. We bridge both worlds — combining enterprise-grade cybersecurity with the operational knowledge of mining hardware, protocols, and threat vectors that generic providers simply don't have.
Our charter is narrow on purpose. We don't do generalist security. We protect mining infrastructure — and we do it better than anyone else.
