Defense.com Review
Operationalize OSINT-sourced threat intelligence inside a managed XDR and SOC platform built for enterprise security teams.
Quick Verdict
Mid-market and enterprise security teams building a structured threat intelligence program that needs a detection platform, not just a research toolset.
Pros
- + Ingests open source and commercial threat intel feeds, including OSINT-sourced IOCs from MISP and VirusTotal
- + Attack surface management module extends external discovery beyond manual recon
- + Managed SOC tier removes analyst overhead for teams that lack in-house capacity
- + 28-day free trial gives full platform access for a serious evaluation
Cons
- − Not a free tool — pricing is opaque and mid-market/enterprise-focused
- − Overkill for individual practitioners or small teams without a formal threat intel program
- − Heavy reliance on managed service model may reduce direct analyst control
- − Integration depth with community OSINT tooling depends on manual workflow setup
What Defense.com Is
Defense.com is a commercial XDR, SIEM, and SOC platform, built by Bulletproof Security, a UK-based managed security provider. It is not free and not an OSINT tool.
Defense.com is designed for threat intelligence practitioners who have outgrown spreadsheets and manual IOC tracking. Practitioners need a platform that acts on OSINT output.
Defense.com operationalizes intelligence. Practitioners gather indicators, track actors, and map infrastructure with OSINT. The platform ingests that intel into detection rules, correlates it against log data, and surfaces actionable alerts.
Defense.com offers four pricing tiers, ranging from entry-level to fully managed SOC. A 28-day free trial is available, with full platform access.

Core Capabilities for Threat Intelligence Practitioners
Defense.com accepts threat intelligence feeds, both commercial and open source. IOCs from OSINT workflows, MISP, and community platforms are accepted. You can feed them directly into the detection layer, eliminating the need to dump them into a spreadsheet.
Your OSINT workflow generates indicators. Simply feed them in and match them against your environment.
The platform handles log aggregation and correlation. You can write detection rules to compare OSINT indicators against your log data, including malicious infrastructure, C2 patterns, and TTPs. The platform correlates the data, and OSINT provides the intelligence.
Log data pours in, the engine matches, and alerts fire. That's the value.
The platform offers continuous asset discovery, both external and internal, with no need for manual scans. Asset discovery tools like Shodan and Censys do this, and now it's a built-in feature.
Your asset inventory stays current with no need for manual refresh. New assets are detected and rules are applied. Threat intelligence teams save time.
OSINT Integration Points
Integration Workflow
In practice, OSINT tooling integration with Defense.com is about workflow, not native connectors. A mature threat intelligence program looks like this.
External infrastructure from Shodan queries feeds into Defense.com's asset inventory. You find exposures — open ports, certificate mismatches, exposed services — then track them.
OSINT indicators from MISP, VirusTotal, get pushed into Defense.com. File hashes, domains, IPs, URLs. The platform correlates them against logs. Your IOC becomes a live detection.
For targeted intel programs, Defense.com maps actor TTPs to detections. OSINT actor profiles, infrastructure clusters, behavioral indicators turn into rule sets. Alerts fire when matching activity appears.
Pricing and Access
Defense.com offers four tiers: Starter, Professional, Enterprise, and Managed SOC. Pricing is available upon request, which is not unusual for mid-market security platforms.
The 28-day free trial provides full access to the platform. During the trial, you can test IOC ingestion from your OSINT tools, validate the attack surface management module against your external footprint, and stress-test SIEM correlation with a log source you control.
The trial is a structured evaluation, not a demo.
The primary buyers of Defense.com are mid-market and enterprise security teams. They typically have an existing OSINT workflow and require a detection platform on top. They also have budget for a managed service. Individual practitioners usually find the free OSINT toolchain sufficient.
Verdict
Defense.com sits on top of your OSINT tools. It provides detection and response capabilities that turn research into operational security. SIEM, threat intel feeds, attack surface management. These features matter to threat intel pros working at scale.
If threat intel is still mostly research — gathering and sharing IOCs, Defense.com isn't the right fit. It's for when you need to feed live detections, drive incident response, and correlate log data at scale.
The 28-day trial lets you test it with real data. See integration friction firsthand. No sales pitches. Just try it.
