isMalicious + Shodan
Internet-connected device search engine. isMalicious consumes this source and correlates it with others — this page explains what that adds, and when to go to the source directly.
Shodan is one of the sources isMalicious aggregates
We are not a replacement for Shodan, and the table below is not a scoreboard. isMalicious ingests or queries Shodan alongside other sources and returns a single weighted verdict. Rows where isMalicious shows a capability Shodan does not are usually capabilities of the aggregation layer, not evidence that our data on Shodan's own specialty is better. For Shodan's primary use case, go to Shodan.
Quick verdict
Choose isMalicious for API-first threat intelligence with multi-source correlation, CVE data, and ransomware tracking. Choose Shodan for attack surface management and internet-wide device discovery.
isMalicious
Real-time threat intelligence API with multi-source correlation, CVE intelligence, and ransomware leak-site tracking.
Best for: Automated threat intelligence at scale
Shodan
Shodan indexes internet-connected devices — servers, routers, cameras, industrial systems — and exposes their open ports, banners, and vulnerability data. It is primarily used for attack surface discovery and research, not real-time threat verdict APIs.
Best for: Attack surface management and internet-wide device discovery

Frequently Asked Questions
Is isMalicious better than Shodan for threat intelligence?
They serve different use cases. Shodan is purpose-built for attack surface discovery — finding exposed devices and open ports across the internet. isMalicious is built for real-time threat intelligence — scoring the reputation of IPs, domains, and URLs and providing verdict APIs for automated security pipelines. Most mature security teams use both.
Does isMalicious include Shodan data?
isMalicious aggregates open-port and banner context alongside configured intelligence sources. For full Shodan-style device enumeration, Shodan remains the better tool. For threat scoring and SIEM/firewall enrichment, isMalicious provides a richer, verdict-focused dataset.
Which is better for SOC teams?
isMalicious is better suited to SOC workflows that need fast, automated enrichment of indicators at scale. Shodan is better for periodic attack surface reviews and proactive exposure management. Many SOC teams use Shodan for asset discovery and isMalicious for real-time alert enrichment.
