# Deepinfo vs. Microsoft Defender EASM

URL: https://www.deepinfo.com/compare/microsoft-defender-easm/

EASM-led

Microsoft Defender EASM suits teams standardized on Azure and the Microsoft security stack that want attack surface data inside it. Deepinfo suits teams that want attack surface management together with breach data, lookalike domains and vendor scanning, without tying it to one cloud.

Both discover assets from seeds and rank what they find. The differences are in what comes with it and how you buy it.

## Compare the Inputs, Outputs and Billing.

Both start from assets you already know and expand from there. What they find, what comes with it and how you pay for it differ.

Deepinfo and Microsoft Defender EASM compared feature by feature

| Capability | Deepinfo | Defender EASM |
| --- | --- | --- |
| The basics |  |  |
| Discovery | From a seed, with subdomain enumeration and reverse IP, MX, NS and WHOIS pivots across Deepinfo’s index | From discovery seeds, recursing through observed connections in Microsoft’s internet data |
| Asset types | Domains, subdomains and IP addresses | Domains, hosts, IP blocks, ASNs, email contacts and WHOIS organizations |
| Scanning | All layers of each asset, from WHOIS to TCP and UDP ports, with history | Web components, certificates, domain records and open ports |
| Where it runs | The Deepinfo Platform, with a REST API | An Azure resource in your subscription |
| Billing | Priced by the scope you monitor | Per approved billable asset, through Azure |
| Ranking and compliance |  |  |
| Vulnerability ranking · Per CVE | CVSS, EPSS and CISA KEV side by side | High, medium and low priorities |
| Known exploited vulnerabilities | CISA KEV status on every CVE | CISA known exploits dashboard |
| Compliance views | Each issue classified against compliance frameworks | GDPR, OWASP Top 10 and CWE Top 25 dashboards |
| Beyond the attack surface |  |  |
| Breached emails and infostealer devices | Yes | Not part of Defender EASM |
| Lookalike domain monitoring | Typos, other extensions and confusable letters | Not part of Defender EASM |
| Vendor scanning on your own scale | Portfolios, same engine and score | Not a dedicated workflow |
| Bulk internet data · All domains, all subdomains, daily changes | API and CSV or JSON feeds | Not part of Defender EASM |
| Getting data out |  |  |
| Exports | REST API, notifications, scheduled PDF reports | REST API (preview), Log Analytics and Azure Data Explorer connections, CSV |

## Where Defender EASM Is Strong.

Inside a Microsoft shop, it is *the short path.*

Defender EASM is provisioned as an Azure resource, billed through your Azure agreement and exported to Log Analytics and Azure Data Explorer, where Microsoft Sentinel and the rest of the Defender stack can use it. A first resource starts with a 30-day free trial.

Its discovery draws on internet data Microsoft built up with RiskIQ, which it acquired in 2021.

Breadth

### All Exposure Areas on One Platform

Attack surface, breach and infostealer data, lookalike domains and vendor scanning share one platform, one set of notifications and reports, and one API. You do not assemble them from separate products.

[Platform](https://www.deepinfo.com/platform/)

Prioritization

### Exploitation Signal on Every CVE

Each CVE carries CVSS, EPSS and its CISA KEV status side by side, plus CWE mapped to OWASP Top 10 2021. The queue starts with what attackers are most likely to use.

[Scoring](https://www.deepinfo.com/platform/easm/complete-risk-scoring/)

Independence

### No Cloud Commitment

Deepinfo runs outside any cloud subscription. Findings leave through the REST API, notifications and scheduled reports, so your team routes them into the tools it already runs.

[Integrations](https://www.deepinfo.com/integrations/)

## Query the Index Behind the Platform.

The index that drives discovery also answers your questions. One call returns all domains that use a given mail server; another returns the domains registered with the same WHOIS email.

Bulk feeds deliver the full domain and subdomain lists, plus daily changes, as CSV or JSON files.

[Reverse MX API](https://www.deepinfo.com/data-api/apis/reverse-mx/)

Request

Reverse MX

```bash
curl "https://api.deepinfo.com/v1/discovery/reverse-mx?mx=mail.acme.example" \
  -H "apikey: YOUR_API_KEY"

## What Buyers Ask About Both.

**Can we use Deepinfo if we run the Microsoft security stack?**

Yes. Deepinfo does not depend on any cloud or SIEM vendor. Findings and data are available through the REST API, notifications and scheduled reports, and the [integrations](https://www.deepinfo.com/integrations/) page lists current connection options.

**How does pricing differ?**

Defender EASM is billed through Azure for each approved billable asset. Deepinfo is priced by the scope you monitor across the modules you use; see [pricing](https://www.deepinfo.com/pricing/) or ask us for a scoped quote.

**What does Deepinfo add beyond attack surface management?**

Breached employee emails and infostealer-compromised devices, lookalike domain monitoring, vendor scanning on the same scale as your surface, and direct access to the underlying index through APIs and bulk feeds.

**Can the two run side by side?**

Yes. Defender EASM can keep exporting to Log Analytics and Azure Data Explorer for Microsoft Sentinel, while Deepinfo adds breach data, lookalike domains, vendor scanning and the index itself. Run both on the same seeds to see where their inventories differ.

**Which compliance frameworks does Deepinfo classify issues against?**

OWASP Top 10 2021, PCI DSS 4.0, PCI DSS 3.2, HIPAA, CWE, CAPEC and WASC. Defender EASM offers GDPR, OWASP Top 10 and CWE Top 25 dashboards.
