Proofpoint TAP - Printing Press CLI

Prerequisites: Install the CLI

This skill drives the proofpoint-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install proofpoint --cli-only
   

2. Verify: proofpoint-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.4 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/monitoring/proofpoint/cmd/proofpoint-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

Existing TAP tools are thin per-endpoint wrappers or one-way SIEM shovels. This CLI syncs clicks, messages, campaigns, VAPs, and clickers into SQLite, then answers joined questions locally - incident briefs, flat IOC tables, risk overlaps, per-user timelines - without re-spending the 1800-per-day SIEM quota or the 50-per-day campaign-ids quota.

When to Use This CLI

Use this CLI when an agent needs Proofpoint TAP threat data: pulling SIEM click/message events, identifying Very Attacked People and top clickers, investigating a threatId or campaign, extracting IOCs for blocking, or decoding urldefense-rewritten links. It shines when questions repeat or cross endpoints - the local store answers joins and re-queries without burning daily API quota.

Anti-triggers

Do not use this CLI for:

• Do not use this CLI for Proofpoint Essentials administration (orgs, users, licensing) - that is a different API with different credentials
• Do not use this CLI to stream PoD message logs - the PoD Log API is a WebSocket service not covered here
• Do not use this CLI to release or manage quarantined messages - quarantine actions live in the PPS admin interface, not the TAP API
• Do not use this CLI to send or simulate phishing tests - TAP is read-only threat intelligence

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Quota-aware threat ops

• backfill - Reconstruct up to 7 days of SIEM threat events in one command - the CLI auto-loops the API's mandatory 1-hour windows and persists every page locally.

  Reach for this when an agent needs more than the last hour of click/message events; single API calls cannot exceed a 1-hour window.

  proofpoint-cli backfill --since 48h --agent
  

• campaign-threats - Expand one campaign into the threats inside it, enriched with severity and family from the local threat store.

  Use this to pivot from a campaign to its member threats when quota is tight - campaign detail is the one unlimited TAP endpoint.

  proofpoint-cli campaign-threats "campaign-xyz789" --agent
  

Incident response

• incident - Turn a threatId into a single incident brief: severity, actors, malware, techniques, forensic evidence, and every local event that touched it.

  Use this for alert triage when you have a threatId and need the full picture in one shot instead of three separate calls.

  proofpoint-cli incident "threat-abc123" --agent
  

• iocs - Flatten TAP's nested forensic evidence tree into a paste-ready indicator table: hashes, URLs, domains, IPs, files, registry keys, processes.

  Use this when the goal is indicators for blocking or hunting, not a narrative brief - output pipes straight into an EDR or blocklist.

  proofpoint-cli iocs --threat-id "threat-abc123" --csv
  

People risk

• risk-overlap - List the people who are both Very Attacked AND top clickers - attack index beside click count - your highest-risk humans.

  The single best list for security-awareness targeting: highly attacked people who also click.

  proofpoint-cli risk-overlap --window 30 --agent
  

• user - Everything the local store knows about one person: clicks, threat messages, VAP status, and clicker status in one view.

  Use this during investigations to answer 'show me every event touching this user' without burning SIEM quota on re-queries.

  proofpoint-cli user "[email protected]" --agent
  

Command Reference

campaign - Campaign intelligence (actors, malware, families, techniques)

• proofpoint-cli campaign get - Get campaign detail (actors, malware, techniques, members)
• proofpoint-cli campaign list-ids - Heavily rate limited (50 requests per rolling 24 hours). Prefer the local synced store for repeated queries.

forensics - Forensic evidence (IOCs) for threats and campaigns

• proofpoint-cli forensics - Provide exactly one of threatId or campaignId.

people - Very Attacked People and top clickers

• proofpoint-cli people list-top-clickers - List users who clicked the most malicious links in a window
• proofpoint-cli people list-vap - List Very Attacked People (highest attack index) for a window

siem - Time-windowed threat event feeds (clicks and messages)

• proofpoint-cli siem list-all-events - Fetch all click and message threat events in the window
• proofpoint-cli siem list-clicks-blocked - Fetch clicks to malicious URLs that were blocked in the window
• proofpoint-cli siem list-clicks-permitted - Fetch clicks to malicious URLs that were permitted in the window
• proofpoint-cli siem list-issues - Events for clicks to malicious URLs permitted and messages delivered containing a known threat within the window - the
• proofpoint-cli siem list-messages-blocked - Fetch blocked messages that contained a known threat
• proofpoint-cli siem list-messages-delivered - Fetch delivered messages that contained a known threat

threat - Per-threat summaries

• proofpoint-cli threat <threatId> - Get a threat summary (severity, spread, actors, malware, techniques)

url - Decode TAP-rewritten (urldefense) URLs

• proofpoint-cli url - Decode TAP-rewritten (urldefense) URLs to their original targets

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

proofpoint-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match - fall back to --help or use a narrower query.

Recipes

Morning triage: what got through overnight

proofpoint-cli backfill --since 12h

Backfill loops the 1-hour windows for you; afterwards search and user answer questions offline.

One-shot incident brief from an alert

proofpoint-cli incident "threat-abc123" --agent --select summary.severity,summary.malware,iocs

Severity, attribution, and evidence for a threatId in a single agent-shaped payload.

Blocklist-ready indicators for a campaign

proofpoint-cli iocs --campaign-id "campaign-xyz789" --csv

Flat CSV of hashes, URLs, and IPs ready for an EDR import.

Awareness-training cohort

proofpoint-cli risk-overlap --window 90 --csv

The people who are both heavily attacked and clicking, with both metrics side by side.

Decode a batch of urldefense links

proofpoint-cli url --urls "https://urldefense.com/v3/__https://example.com__;!!abc" --agent --select urls.decodedUrl,urls.success

Returns the real target URLs; works even without credentials.

Auth Setup

TAP uses HTTP Basic auth with a service principal and secret. In the TAP Dashboard go to Settings, then Connected Applications, and create a new credential pair. Export PROOFPOINT_SERVICE_PRINCIPAL and PROOFPOINT_API_SECRET in your shell. The url decode command works without credentials; everything else requires them.

Run proofpoint-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable - JSON on stdout, errors on stderr

• Filterable - --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  proofpoint-cli campaign get <id> --agent --select id,name,status
  

• Previewable - --dry-run shows the request without sending

• Offline-friendly - sync/search commands can use the local SQLite store when available

• Non-interactive - never prompts, every input is a flag

• Explicit retries - use --idempotent only when an already-existing create should count as success

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set - piped/agent consumers and explicit-format runs get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

proofpoint-cli feedback "the --since flag is inclusive but docs say exclusive"
proofpoint-cli feedback --stdin < notes.txt
proofpoint-cli feedback list --json --limit 10

Entries are stored locally at ~/.local/share/proofpoint-cli/feedback.jsonl. They are never POSTed unless PROOFPOINT_FEEDBACK_ENDPOINT is set AND either --send is passed or PROOFPOINT_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

proofpoint-cli profile save briefing --json
proofpoint-cli --profile briefing campaign get <id>
proofpoint-cli profile list --json
proofpoint-cli profile show briefing
proofpoint-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
