Resensor vs CyCognito
CyCognito is an enterprise external attack surface management platform, built around large-scale automated reconnaissance, asset attribution and active security testing. Resensor brings the same outside-in discipline in a focused, self-serve product, ranking what an attacker is most likely to exploit with CISA KEV and FIRST EPSS. Here is an honest comparison, including where each one leads.
Same philosophy, different shape. CyCognito is enterprise EASM: large-scale reconnaissance, graph-based asset attribution and active testing, delivered through enterprise sales to large, complex organizations. Resensor is focused, self-serve EASM: it discovers your external surface, then validates and ranks what an attacker is most likely to exploit with CISA KEV and FIRST EPSS, shows the evidence behind each finding, and adds coverage of open cloud storage and datastores, exposed AI services, email spoofability, typosquatted domains, and third-party vendor ratings, all with transparent pricing and a free start.
How they compare
| Dimension | CyCognito | Resensor |
|---|---|---|
| Center of gravity | Enterprise EASM with large-scale recon and active testing | External attack surface management plus evidence-based exposure validation |
| Discovery approach | Automated reconnaissance and graph-based asset attribution at scale | External discovery: subdomains, certificates, services, network seeding and cloud connectors |
| Exploit prioritization | Risk-based scoring | CISA KEV and FIRST EPSS, ranked by real-world exploitability, shown on every finding |
| Validation approach | Includes active security testing | Evidence-based and non-destructive: reachability re-check, screenshots, proof |
| Exposed cloud data | Surfaces exposed assets | Open S3, GCS and Azure buckets; anonymous Redis, Mongo and Elasticsearch; secrets in client JavaScript |
| AI surface discovery | Not a focus | Exposed model servers, vector databases, MCP, and notebooks |
| Brand and typosquat | Not a focus | Look-alike domain detection plus takedown packets |
| Third-party vendor ratings | Not a focus | Lookout vendor monitoring |
| Pricing and onboarding | Enterprise sales, quote-based | Self-serve, transparent per-domain, free to start |
| Best fit | Large, complex enterprises wanting recon and active testing at scale | Teams and MSPs wanting the external attacker view, prioritized, fast |

Where each one leads
Where CyCognito leads
- Large-scale automated reconnaissance and graph-based asset attribution
- Enterprise-grade EASM with active security testing at scale
- A strong fit for very large, complex organizations and subsidiaries
- The stronger pick if you need heavyweight recon and active testing across a sprawling estate
Where Resensor leads
- The same outside-in view, self-serve and transparently priced
- Exploit-aware prioritization with CISA KEV and FIRST EPSS on every finding
- Exposed cloud data, AI services, email spoofability, and brand abuse in one place
- Evidence behind every finding, third-party vendor ratings, and MSP rollup, fast to value
What Resensor does not do
To be precise: Resensor validates from evidence and stays non-destructive. It does not fire intrusive exploit payloads or run breach-and-attack simulation, and it is not sold as a heavyweight enterprise engagement. If your priority is large-scale reconnaissance with active testing across a sprawling, multi-subsidiary estate and a sales-led rollout, CyCognito is built for that. Resensor's job is a focused, self-serve external view, validated and ranked by real-world exploitability, that a team can stand up in minutes. The two share a philosophy and differ on shape and scale.
The attacker's full external view, prioritized
If you want the outside-in attacker view without an enterprise procurement cycle, that is Resensor: continuous external discovery, then evidence-based validation with CISA KEV and FIRST EPSS, plus coverage of cloud data exposure, exposed AI services, email spoofability across SPF, DKIM and DMARC, and typosquatted look-alike domains.

How is Resensor different from CyCognito?
Both take the outside-in attacker view. CyCognito is an enterprise EASM platform built around large-scale automated reconnaissance, asset attribution and active security testing, typically sold through enterprise sales. Resensor brings the same external discipline in a focused, self-serve product with transparent pricing, ranking findings by real-world exploitability with CISA KEV and FIRST EPSS and adding coverage of cloud data, AI, email and brand.
Is Resensor built for enterprises like CyCognito?
CyCognito is designed for large, complex enterprises with sales-led onboarding and active testing at scale. Resensor is self-serve and transparently priced, which suits teams and MSPs that want a fast, prioritized external view without an enterprise procurement cycle. Larger organizations use Resensor too, but its strength is fast time to value and clarity over heavyweight deployment.
Does Resensor run active exploitation like some EASM platforms?
No. Resensor validates exploit likelihood from evidence: CISA KEV, FIRST EPSS, breach data and the exposure signals it observes from the outside, with reachability re-checks and screenshots. It does not fire intrusive exploit payloads or run breach-and-attack simulation, so scans stay safe to run against production.
What does Resensor cover beyond core attack surface discovery?
Open cloud storage buckets and anonymous datastores, secrets leaked in client-side JavaScript, exposed AI services such as model servers and vector databases, email spoofability across SPF, DKIM and DMARC, typosquatted look-alike domains with takedown packets, and third-party vendor ratings. Each is ranked by real-world exploitability with the evidence shown behind it.
