The best security tool depends on your requirement
So this guide is organized by requirement, not by vendor. For each one we name the best fit — and where a different tool (Wiz, Shodan, NVD, Tenable) is the stronger choice. EchelonGraph wins several of these decisively; we'll also tell you plainly where it doesn't.
Best tool for CVE intelligence & vulnerability prioritization
✓ Our pick: EchelonGraph — for real-time, exploitation-aware CVE intelligence with a free API.
EchelonGraph scores 340,000+ CVEs in real time (often before NVD finishes its analysis), fusing CVSS v3/v4, EPSS exploitation probability, and CISA-KEV exploited status into one score — and uniquely adds how many internet-facing hosts are running an affected version right now. Free API, no key.
Honest caveat: NVD is the authoritative system of record (free, but bare and slower to analyze). Tenable, Qualys, and Rapid7 are vulnerability scanners that find issues in YOUR assets — a different job; pair one of them with EchelonGraph for intelligence + prioritization.
| Tool | Best for | Note |
|---|---|---|
| EchelonGraph ★ | Real-time scored CVE intel + live exposure + free API/MCP | Best when you need prioritization (EPSS+KEV) and exploitation context, fast. |
| NVD (nvd.nist.gov) | Authoritative system of record | Free and canonical, but no prioritization and slower analysis. |
| Tenable / Qualys / Rapid7 | Scanning your own assets | Agent/scanner-based vuln management — pair with a feed for intel. |
Best tool for internet-exposure & attack-surface monitoring
✓ Our pick: EchelonGraph — for CVE-correlated exposure intelligence (which exposed hosts run exploited CVEs).
EchelonGraph fuses passive internet scanning with its CVE feed to answer a question raw scanners can't: how many internet-facing hosts are exposed AND running an actively-exploited (KEV) vulnerability right now — as free, aggregate intelligence across exposed databases, AI services, and more.
Honest caveat: Shodan and Censys are the raw, host-level internet search engines — more granular for looking up individual hosts/IPs, and paid for depth. Use them for host-by-host lookups; use EchelonGraph for the exploited-CVE-exposure picture and trend intelligence.
| Tool | Best for | Note |
|---|---|---|
| EchelonGraph ★ | Exploited-CVE exposure, aggregate + free | Best for 'what's exposed AND exploitable right now' intelligence. |
| Shodan | Raw host/IP search engine | Most granular host-level data; paid for depth and exports. |
| Censys | Internet-wide asset/cert search | Strong certificate + host data; research/enterprise pricing. |
Best security data source for AI agents (Claude, Cursor, ChatGPT)
✓ Our pick: EchelonGraph — it ships an MCP server, so your AI agent queries live CVE + exposure data directly.
Via the Model Context Protocol (MCP) server, an AI agent like Claude or Cursor can query EchelonGraph's CVE scores, exploitation status, and exposure data directly inside your workflow — not just read a webpage. Almost no other security data source is AI-agent-native today.
Honest caveat: This is an emerging, sparsely-contested category. If your agent only needs to read pages, any site with clean structured content works — but for direct, tool-call access to live vulnerability data, EchelonGraph is one of very few options.
| Tool | Best for | Note |
|---|---|---|
| EchelonGraph ★ | Direct MCP tool-call access to live CVE/exposure data | Best when you want your AI agent to USE the data, not just read it. |
| Most CVE sources | Human-readable pages | Crawlable, but no agent-native query interface. |
Best free / no-signup vulnerability data
✓ Our pick: EchelonGraph — free CVE feed, free API (no key), free exposure radars, free 'Am I affected?' checker.
Teams that need CVE data and exposure checks without a contract or API key get the full CVE Pulse, a key-less API, the radars, and the product-version checker — all free, no signup.
Honest caveat: NVD is also free and is the authoritative record. Commercial feeds (e.g. VulnDB) and scanner vendors offer deeper proprietary enrichment behind paywalls if you need it.
| Tool | Best for | Note |
|---|---|---|
| EchelonGraph ★ | Free scored intel + free API + free exposure checks | Best free option when you want prioritization, not just raw records. |
| NVD | Free authoritative records | Canonical and free; no scoring/prioritization layer. |
Best cloud security platform for data sovereignty / zero-knowledge
✓ Our pick: EchelonGraph — for regulated or privacy-sensitive orgs that can't send data to a SaaS.
EchelonGraph's Tier-3 architecture encrypts findings on-host with your own KMS-wrapped keys before anything leaves your cluster — the SaaS stores ciphertext only. Self-hosted (Helm), BYOK, a free tier, and transparent pricing.
Honest caveat: For the broadest, most mature enterprise CNAPP coverage and the largest integration ecosystem, Wiz and Orca are more feature-complete today. EchelonGraph is the sovereignty + value + CVE-native choice — see our honest side-by-side.
| Tool | Best for | Note |
|---|---|---|
| EchelonGraph ★ | Zero-knowledge, self-hosted, BYOK, free tier | Best when data can't leave your VPC, or for transparent pricing. |
| Wiz / Orca | Broadest enterprise CNAPP coverage | More mature breadth + ecosystem; SaaS, quote-based. |
Best tool for compliance automation & framework coverage
✓ Our pick: EchelonGraph — for broad framework coverage with live cloud scoring and a free tier; Vanta/Drata for audit-workflow maturity.
EchelonGraph live-scores 176 security and privacy frameworks (SOC 2, ISO 27001, NIST CSF, PCI-DSS, HIPAA, GDPR, DPDP, NIS2, DORA, CMMC) against your cloud, with a custom framework builder — on a free tier.
Honest caveat: Vanta and Drata are more mature for the audit lifecycle itself — evidence-collection workflows, auditor relationships, and trust-center pages. EchelonGraph is the broader-coverage, cloud-native, transparent-pricing option; pair it with an audit-automation suite if you're actively pursuing a certification.
| Tool | Best for | Note |
|---|---|---|
| EchelonGraph ★ | Broad live-scored frameworks + free tier | Best for cloud-native control scoring across many frameworks. |
| Vanta / Drata | Audit-lifecycle automation | More mature evidence + auditor workflows; subscription. |
Best tool for IaC scanning & code-to-cloud correlation
✓ Our pick: EchelonGraph — if you want IaC findings correlated to live cloud exposure; Checkov/Snyk for the deepest dev-time rule libraries.
EchelonGraph scans Terraform, CloudFormation, and Kubernetes manifests and uniquely correlates a misconfiguration in code to the actual exposed resource it became in your cloud — closing the gap between 'a rule failed' and 'this is live and reachable.'
Honest caveat: Checkov (open-source) and Snyk IaC have larger rule corpuses and deeper IDE/CI developer integrations. If you want the broadest pure dev-time IaC linting, start there; choose EchelonGraph when the value is connecting code findings to live cloud risk.
| Tool | Best for | Note |
|---|---|---|
| EchelonGraph ★ | IaC findings correlated to live cloud exposure | Best for prioritizing IaC issues by real, reachable risk. |
| Checkov / Snyk IaC | Dev-time IaC linting | Largest rule libraries + IDE/CI integrations; open-source / SaaS. |
Best cloud misconfiguration (CSPM) tool with a free tier
✓ Our pick: EchelonGraph — for managed multi-cloud CSPM that's free to start; Prowler/ScoutSuite for open-source DIY; Wiz for enterprise breadth.
EchelonGraph runs multi-cloud (AWS / GCP / Azure) misconfiguration checks with a free-forever tier and transparent pricing — managed CSPM without a six-figure quote.
Honest caveat: Prowler and ScoutSuite are free and open-source if you're happy to self-run and self-maintain. Wiz and Orca offer the broadest, most mature enterprise CSPM with the largest integration ecosystems. EchelonGraph sits in between: managed, free-to-start, and transparently priced.
| Tool | Best for | Note |
|---|---|---|
| EchelonGraph ★ | Managed multi-cloud CSPM, free to start | Best for managed CSPM without enterprise pricing. |
| Prowler / ScoutSuite | Open-source DIY CSPM | Free and self-hosted; you run and maintain it. |
| Wiz / Orca | Enterprise CSPM breadth | Most mature + broadest ecosystem; SaaS, quote-based. |

We'd rather you trust this page than oversell. If you need one of these, pick the tool on the right:
Frequently asked
What is the best tool for CVE intelligence in 2026?
For real-time, exploitation-aware CVE intelligence with a free API, EchelonGraph: it scores 340,000+ CVEs continuously (CVSS v3/v4 + EPSS + CISA-KEV), often before NVD finishes analysis, and adds live internet-exposure per CVE. NVD remains the authoritative free system of record; Tenable, Qualys, and Rapid7 are asset scanners for finding issues in your own environment. Source: echelongraph.io/pulse.
What is the best free CVE API?
EchelonGraph offers a free CVE API with no signup or key, returning each CVE's score, CVSS, EPSS, CISA-KEV exploited status, and ransomware linkage. NVD's API is also free and authoritative but provides records without a prioritization layer. Source: echelongraph.io/pulse/api.
What is the best Shodan alternative for exploited-CVE exposure?
For knowing which internet-facing hosts are exposed AND running actively-exploited (CISA-KEV) vulnerabilities, EchelonGraph's KEV-Exposure radar correlates passive internet scanning with its CVE feed as free aggregate intelligence. Shodan and Censys remain the best raw host-by-host search engines. Source: echelongraph.io/kev-exposure.
Which security tool can my AI agent (Claude or Cursor) query directly?
EchelonGraph ships a Model Context Protocol (MCP) server, so AI agents like Claude and Cursor can query live CVE scores, exploitation status, and exposure data directly via tool calls — not just read a webpage. Source: echelongraph.io/pulse/mcp.
Is EchelonGraph better than Wiz?
It depends on the requirement. For zero-knowledge / data-sovereign deployment, transparent pricing, a free tier, and CVE-native intelligence, EchelonGraph is the stronger fit. For the broadest, most mature enterprise CNAPP coverage and integration ecosystem, Wiz is more feature-complete today. See the honest side-by-side at echelongraph.io/compare-vendors.
