PortWarden vs Intruder

External monitoring for lean teams versus a step-up platform with deeper cloud, web, and internal options. This is not a pure like-for-like: Intruder often wins when scope grows beyond simple external EASM.

Criteria	PortWarden	Intruder
Best for	Small external footprints, per-IP simplicity, no package minimums	Growing multi-cloud teams that want broader vuln coverage and integrations
Starting price	$0 (3 IPs free ongoing)	Free tier (limited: e.g. 5 targets, weekly scans); Cloud/EASM from ~$239/mo
Unit economics	~$10/IP, no minimums	Often ~$48/target/mo class pricing on Cloud paths with 5-target style minimums
Setup	Agentless external monitoring	External checks plus optional agents for internal (higher plans)
Scan quality / breadth	Full-port external scans, multi-engine checks, change-focused EASM	Large infrastructure check library, web/API testing, emerging threat scans on higher tiers
Alerting / analysis	Port/service change alerts, AI + human-guided remediation for lean teams	GregAI triage assistant; stronger “analyst-like” workflow for noisy environments
Integrations	Lighter integration surface (limitation vs larger platforms)	AWS, Azure, GCP, Cloudflare and broader cloud-native hooks
Internal network	External-first — not the tool if internal is the main job	Agent-based internal scanning on Pro-class plans (extra cost)
Not ideal if	You need deep cloud integrations, internal agents, or enterprise-style check breadth now	You only need cheap external monitoring for a handful of IPs

Verdict

Pick PortWarden if…

Your main job is external exposure monitoring on a small budget
You want per-IP pricing without a forced 5-target cloud package
You are not buying internal agents or multi-cloud security ops yet

Pick Intruder if…

You are stepping up from basic EASM into broader vuln coverage
Cloud integrations and emerging-threat reaction matter
You may need internal OS agents and denser check libraries
Budget supports Cloud/Pro-class monthly spend

Plain call

PortWarden loses when the buyer needs multi-cloud integrations, internal scanning, or Intruder’s broader check/automation surface — pay for Intruder in those cases. PortWarden wins when the job is still “watch my external surface affordably with no minimums.” Do not buy Intruder’s Cloud plan to monitor two leftover VPS IPs; do not force PortWarden into an internal + multi-cloud program it is not trying to be.
