Honest, requirement-by-requirement · including where we're NOT the best fit

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 (measured on an exact-grid comparison, we publish new CVEs 16-35 minutes before NVD does, because we read MITRE's cvelistV5 every 5 minutes), each by a published first-match rule over CVSS v3/v4, EPSS exploitation probability and CISA-KEV exploited status — and adds, for the products its KEV-Exposure radar tracks, how many internet-facing services it has on record running an affected version, derived from Shodan data. 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.

ToolBest forNote
EchelonGraph ★Scored CVE intel + Shodan-derived exposure counts + free API/MCPBest when you need prioritization (EPSS+KEV) and exploitation context, fast.
NVD (nvd.nist.gov)Authoritative system of recordFree and canonical, but no prioritization and slower analysis.
Tenable / Qualys / Rapid7Scanning your own assetsAgent/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 (how many exposed services run exploited CVEs).

EchelonGraph matches Shodan banner data against its CVE feed to answer an aggregate question: how many internet-facing services run a version affected by an actively-exploited (KEV) or high-EPSS vulnerability, across the products its KEV-Exposure radar tracks, searched every 12 hours when Shodan query credits allow — as free, aggregate intelligence, alongside separate radars for 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.

ToolBest forNote
EchelonGraph ★Exploited-CVE exposure, aggregate + freeBest for 'what's exposed AND exploitable' intelligence, in aggregate.
ShodanRaw host/IP search engineMost granular host-level data; paid for depth and exports.
CensysInternet-wide asset/cert searchStrong 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 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.

ToolBest forNote
EchelonGraph ★Direct MCP tool-call access to CVE/exposure dataBest when you want your AI agent to USE the data, not just read it.
Most CVE sourcesHuman-readable pagesCrawlable, 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.

ToolBest forNote
EchelonGraph ★Free scored intel + free API + free exposure checksBest free option when you want prioritization, not just raw records.
NVDFree authoritative recordsCanonical 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) and BYOK.

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 + CVE-native choice — see our honest side-by-side.

EchelonGraph ★Zero-knowledge, self-hosted, BYOKBest when data can't leave your VPC.
Wiz / OrcaBroadest enterprise CNAPP coverageMore mature breadth + ecosystem; SaaS.

Best tool for compliance automation & framework coverage

✓ Our pick: EchelonGraph — for broad framework coverage with live cloud scoring; Vanta/Drata for audit-workflow maturity.

EchelonGraph live-scores 330 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.

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 option; pair it with an audit-automation suite if you're actively pursuing a certification.

EchelonGraph ★Broad live-scored frameworksBest for cloud-native control scoring across many frameworks.
Vanta / DrataAudit-lifecycle automationMore mature evidence + auditor workflows; subscription.

Best tool for IaC scanning & code-to-cloud correlation

✓ Our pick: EchelonGraph — if you want IaC findings correlated to what is actually exposed in your cloud; Checkov/Snyk for the deepest dev-time rule libraries.

EchelonGraph scans Terraform, CloudFormation, and Kubernetes manifests and 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 deployed 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.

Checkov / Snyk IaCDev-time IaC lintingLargest rule libraries + IDE/CI integrations; open-source / SaaS.

Best managed multi-cloud misconfiguration (CSPM) tool

✓ Our pick: EchelonGraph — for managed multi-cloud CSPM; Prowler/ScoutSuite for open-source DIY; Wiz for enterprise breadth.

EchelonGraph runs multi-cloud (AWS / GCP / Azure) misconfiguration checks as a managed service — no scanners for you to run and maintain.

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, multi-cloud, and self-hostable.

Where EchelonGraph is not your best fit

We'd rather you trust this page than oversell. If you need one of these, pick the tool on the right:

A raw, host-by-host internet search engine→ Shodan or Censys
The most mature, broadest enterprise CNAPP with the largest integration ecosystem→ Wiz or Orca
Endpoint detection & response (EDR)→ CrowdStrike, SentinelOne, or Microsoft Defender
A SIEM / log-analytics platform→ Splunk, Elastic, or a cloud-native SIEM

Frequently asked

What is the best tool for CVE intelligence in 2026?

For 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 Shodan-derived internet-exposure counts for the CVEs its KEV-Exposure radar tracks. 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 how many internet-facing services run a version affected by actively-exploited (CISA-KEV) vulnerabilities, EchelonGraph's KEV-Exposure radar matches Shodan banner data against 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 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 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.
