Spakto continuously maps every internet-exposed asset, forgotten domain, misconfigured service, and shadow infrastructure — giving you the attacker's view of your external attack surface before threat actors exploit it.

Exposure Alerting
Your biggest risks are
assets you forgot existed.
Traditional inventory lists what IT manages. Spakto EASM maps what the internet can see — shadow IT, expired subdomains, leaked credentials, and misconfigured cloud services no one monitors. Attackers run recon 24/7. Now you do too.
Everything visible
to an attacker.
Six attack surface categories. Every asset discoverable from the internet — whether you know it exists or not.
Continuous DNS enumeration using certificate transparency logs, passive DNS replication, zone transfer attempts, and brute-force permutation — discovering every resolvable hostname under your apex domains.
What attackers see
before they strike.
This is the actual recon playbook attackers run against organizations. Spakto runs it first, continuously — so you find exposures hours before threat actors do.
Continuous internet recon
on your behalf.
Seed
Define your known starting points
- Input your known apex domains, IP ranges, ASN numbers, and company names
- No agents, no firewall rules, no internal network access required
- Works from a single domain — discovery expands automatically
- M&A mode: add target company name and let EASM discover everything
Inventory shows what you manage.
EASM shows what attackers see.
Your IT inventory scores 100% — 5 of 5 known assets are healthy. Meanwhile attackers find 307 more assets you never knew existed. Compliance ≠ security.
Real-time threat signals
from 6 intelligence feeds.
Spakto aggregates live signals across certificate transparency, breach databases, dark web feeds, passive DNS, and code repositories — correlating everything to your attack surface in real-time.
8 recon methods.
All running continuously.
These are the exact techniques professional threat actors use to map your infrastructure. Spakto runs all 8 simultaneously — giving you attacker-equivalent reconnaissance coverage before they do.
Every SSL/TLS certificate issued anywhere on the internet is logged publicly in CT logs. Spakto monitors these logs in real-time, discovering new subdomains seconds after their certificate is issued — before the DNS even propagates.
Discovers 60–80% of all subdomains — including internal names leaked via wildcard SAN fields
Who uses External
Attack Surface Management.
From SOC teams needing real-time alerts to M&A advisors assessing acquisition targets — Spakto gives every security role the external attacker view they've been missing.
SecOps teams use Spakto EASM as their continuous external watchdog — replacing quarterly pen tests and manual surface reviews with an always-on attacker-perspective feed that integrates directly into existing SOC workflows.
- Instant Slack / PagerDuty / Jira alerts when new exposure appears
- New subdomain with open admin panel — alerted within 4 minutes
- Credential leak in GitHub triggers automatic asset correlation
- SIEM integration: findings as structured events with IOC context
“We found a Jenkins instance with default credentials on a subdomain we didn't know existed. It had been there for 11 months.”

External Attack Surface Management FAQs
Frequently asked
questions.
answered
No. External Attack Surface Management works entirely from the internet perspective — no agents, no internal network access, no firewall changes required. We discover what attackers can see from outside.
Subdomain takeover occurs when a DNS record points to a cloud service (S3, GitHub Pages, Heroku) that has been deprovisioned — allowing an attacker to claim the service and serve content under your domain. Spakto continuously monitors for these conditions.
Yes. Spakto can assess the external attack surface of acquisition targets using only publicly available information — no access to the target's systems required. This provides critical risk context before a deal closes.
Bug bounty programs rely on researchers to report individual findings. Spakto provides continuous, comprehensive attack surface coverage — finding exposures 24/7, not just when a researcher happens to look.
We use the same techniques attackers use: certificate transparency logs, passive DNS, WHOIS analysis, ASN enumeration, web crawling, GitHub/GitLab search, and more. If it's discoverable from the internet, we'll find it.
Most new exposures are detected within minutes of appearing. Our continuous monitoring cadence means you're alerted to new attack surface before attackers have time to exploit it.
Yes. We monitor public code repositories (GitHub, GitLab, Pastebin), credential breach databases, and data leak sites for exposed credentials, API keys, and sensitive data tied to your organization's domains and email addresses.
