Harmony Endpoint (TAC-Grade) Deployment Runbook: Design, Readiness, Pilot & Rollout Rings
Scope (to avoid confusion in the field)
This runbook covers Harmony Endpoint only (Windows/macOS/Linux) and focuses on controlled rollout, stability, tuning, and day-0/1 operational readiness. It intentionally excludes Harmony Connect and Harmony Mobile.
Thesis (what matters in production)
Most “Endpoint failures” during rollout are not malware-related—they’re compatibility, connectivity, policy targeting, or too many variables changed at once. The fastest path to low MTTR is: minimize variables, deploy in rings, and collect evidence early.
1) Phase 0 — Planning that actually prevents incidents
1.1 Build a compatibility matrix (not just an asset list)
Map endpoints by:
-
OS + build level (Windows 10/11 by build; macOS major/minor; Linux distro family)
-
Device class (workstation, VDI, kiosk, jump host, regulated endpoints)
-
“Sensitive” software stack: existing VPN, DLP, EDR/AV, inventory agents, hardening tools, dev tools (Docker/WSL), drivers
-
Connectivity profile: direct internet vs explicit proxy vs authenticated proxy, SSL inspection, split DNS
-
Constraints: offline/air-gapped, no local admin, heavily regulated environments
TAC deliverable: a table like Device Class → driver/agent stack → risk/impact.
1.2 Conflict handling (where pilots usually die)
-
Remove legacy AV/EDR in waves, validating each wave.
-
If coexistence is unavoidable, treat it as an exception with an expiry plan and measurable KPIs: crash rate, boot/login time, CPU/IO, detection noise.
1.3 Policy targeting model (don’t run a single “pilot group”)
Use at least two pilot tracks:
-
Pilot-IT (higher tolerance for friction)
-
Pilot-Business (real workflows and real pain)
Then predefine production rings:
-
High-Risk (admins/jump hosts)
-
VDI/Shared (performance-tuned)
-
Exec/Board (stability-first)
1.4 Define go/no-go KPIs before you install anything
Minimum gates (example):
-
installation success rate
-
incidents per 100 endpoints
-
boot/login impact
-
CPU/IO p95 at peak
-
alerts per endpoint/day
-
validated false-positive rate
2) Phase 1 — Pilot execution (Infinity Portal + controlled rollout)
2.1 Portal prep
2.2 Deployment Policy = ring strategy (not “push to all”)
In Policy → Deployment Policy → Software Deployment, roll out via rings:
-
Pilot-IT
-
Pilot-Business
-
Wave 1 (20–30%)
-
Wave 2 (50–70%)
-
Full
Rule: a ring only advances when the previous ring’s KPIs are within the agreed thresholds.
3) Component sequencing (the practical order that reduces tickets)
Step 1 — Baseline protection + stability
Step 2 — Advanced prevention (where false positives appear)
-
Anti-Bot, Anti-Ransomware, Behavioral Guard, Forensics
-
Threat Emulation / Anti-Exploit (where applicable)
This is usually where dev tools, scripts, and internal apps trigger compatibility tuning.
Step 3 — “Operational controls” (common ticket generators)
-
Firewall, Application Control, Port Protection
-
Media Encryption (if used)
These modules affect user experience and can block traffic/apps—deploy only after baseline is stable.
Step 4 — High-impact / high-coupling components
-
Full Disk Encryption (FDE)
-
Remote Access VPN (if the endpoint also runs Check Point VPN)
-
Compliance/Posture (if used)
TAC stance: treat FDE and VPN as projects inside the project with their own gates, comms, and recovery flows.
4) Expand to production only after telemetry proves stability
Before scaling:
Exception governance (don’t create permanent global holes)
Every exception must be:
-
scoped to a Virtual Group
-
justified (incident/FP/audit)
-
time-bounded (review date)
-
validated in a small ring before wider rollout
Next (Part 2): Day-2 operations, upgrades without drift, TAC-style runbooks, and the metrics that prove stability to SecOps and to IT.
