Gartner CTEM: continuous, not quarterly

The assets you forgot you owned are the ones attackers find first

Attack surface management is the continuous process of discovering every internet-facing asset your organization owns, then monitoring each one for exposure before an attacker reaches it. It covers the assets you know about, the ones you forgot, and the ones a developer created without telling anyone.

Attackers do not start with your flagship application. They start with your forgotten one: the subdomain a contractor spun up in 2023, the staging server nobody decommissioned, the storage bucket a developer opened for a five-minute test. Traditional scanners cannot help here, because they test a list you hand them, and the assets that breach you are missing from that list.

Whether you are an IT manager at a 30-person company, a DevSecOps engineer connecting cloud accounts, or a CISO tracking exposure for compliance, ScanTitan gives you attacker-perspective discovery without the enterprise-grade complexity.

How ScanTitan's attack surface management works

A continuous loop that mirrors the Gartner exposure model: discover, assess, prioritize, validate, then monitor. Every pass starts from a single seed and expands outward the way an attacker would.
Discover from a single seed

Enter one domain and ScanTitan enumerates subdomains, IP ranges, cloud services, login pages, APIs, and exposed services using certificate transparency logs, passive DNS, and WHOIS data. The first pass is passive, so it never touches your production systems.

Assess what is actually exposed

ScanTitan fingerprints each discovered asset: its software, open ports, running services, and certificate health, building a live picture of what an outsider can reach right now, not what your spreadsheet says you own.

Separate known from shadow

Every discovered asset is compared against the inventory you can actually name. The delta, the unmanaged assets, gets flagged as shadow IT with a first-seen date and an owner so nothing stays invisible.

Flag subdomain takeover risk

ScanTitan detects dangling DNS records pointing at deprovisioned cloud services, the exact condition an attacker uses to claim a live host on your own domain, before that record becomes a phishing page.

Connect your cloud accounts

Link AWS, Azure, and Google Cloud so ScanTitan inventories cloud assets from the inside and cross-checks them against what is reachable from the outside, catching the public bucket a developer opened and forgot.

How ScanTitan's attack surface management works
Validated exposure, not a theoretical alert

A CVE existing on a host is theoretical. An attacker being able to reach that host and exploit it is validated. ScanTitan confirms reachable exposure before it reaches your queue, so your team sees confirmed risk, not a wall of unverified findings.

Findings are scored on reachability, exploitability, and business impact, not raw severity alone. ScanTitan uses EPSS (Exploit Prediction Scoring System) to weight findings by the probability a flaw gets exploited in the wild, and it surfaces toxic combinations: individually low-severity issues that become critical when they land on the same asset.

The difference, An exposed port, a known exploit, and a path to sensitive data are each low priority alone. On the same asset, they are the first thing to fix. ScanTitan ranks that combination to the top so a lean team fixes the genuine priority, not the loudest one.

Continuous by default, not a quarterly snapshot

Your attack surface changes every time an engineer provisions a resource, so a one-time scan is outdated within hours. ScanTitan re-scans on a schedule and reacts to change, kicking off a new assessment when a fresh subdomain appears or a new cloud service spins up.

When a new critical CVE drops, ScanTitan checks your entire discovered surface against it automatically, so you learn you are exposed before the exploit is weaponized rather than after. This is the operational core of a Gartner CTEM program. 

Why it matters, A forgotten asset that goes live on a Tuesday gets assessed on Tuesday, not at the next audit. Continuous coverage is what turns attack surface management from a compliance checkbox into an actual reduction in the window an attacker has to work with.

Discovery without prioritization is just a longer list

Most tools hand a lean team a raw dump of every finding. ScanTitan hands them a ranked queue, scored on reachability, exploitability, and business impact, so one person can triage in an hour instead of a day.

Every exposure is validated as reachable before it reaches your dashboard, and each one explains what it is, why it is exposed, and how to close it. Attacker’s-eye, not probability-based. 

Reachability scoring

Every finding is weighted by whether an outsider can actually reach it, so an internet-facing panel outranks a theoretical issue on an internal host.

EPSS exploit prediction

Findings are weighted by the probability a flaw gets exploited in the wild, not raw CVSS alone, so the queue reflects real-world attacker behavior.

Toxic combination detection

Individually low-severity issues that become critical on the same asset, an open port plus a known exploit plus a path to data, get surfaced together.

Owner and first-seen tagging

Every shadow asset ships with an owner and a first-seen date, so remediation becomes a targeted fix instead of a ticket nobody claims.

Seven capabilities. One attack surface.

Each capability maps to a dedicated deep-dive page. Together they cover the full external footprint: the assets you know about, the ones you forgot, and the ones nobody logged.

 

Asset Discovery

Enumerate subdomains, hosts, and IP ranges from a single seed using certificate transparency logs, passive DNS, and WHOIS. Flags subdomain takeover risk before it becomes a phishing host.

Shadow IT Discovery

Surface the assets IT does not know it owns: the unmanaged host, the trial SaaS account, the API a contractor left running. The delta against your known inventory, with an owner attached.

Open Port Enumeration

Scan discovered hosts for open ports and fingerprint the service and version behind each one, so an exposed database on 3306 or admin panel on 8080 links straight to known CVEs.

SSL/TLS Certificate Monitoring

Track every certificate across your assets. Alert before expiry, not after the outage, and flag weak ciphers, self-signed certs on production, and mismatched hostnames.

Cloud Asset Exposure

Catch cloud resources with provider-assigned addresses that sit outside your DNS: public S3 buckets, Azure Blob containers, serverless endpoints, and orphaned resources across AWS, Azure, and GCP.

Continuous ASM Monitoring

Re-scan on a schedule and react to change. A new subdomain or cloud service triggers a fresh assessment, and every new critical CVE is checked against your full surface automatically.

Risk Prioritization & Scoring

Score each exposure on reachability, exploitability, and business impact using EPSS, and surface toxic combinations so the top of your queue is genuinely the thing to fix first.

EASM vs vulnerability scanning, CAASM, and CSPM

These four acronyms overlap enough to confuse a budget conversation. A vulnerability scanner cannot test the asset it never knew existed. EASM finds it first, which is why attack surface management sits upstream of everything else in your program.
Category What it does Perspective Starts from Best for
EASM Discovers unknown internet-facing assets, then flags exposure Outside-in A seed domain, no list needed Finding shadow and forgotten assets

Common questions about attack surface management

Answered by our security team, not by a chatbot.

Attack surface management (ASM) is the broad discipline covering your full attack surface, internal and external. External attack surface management (EASM) is the subset focused on internet-facing assets, the ones any outsider can reach without first getting inside your network. In ScanTitan, attack surface management works on the external side: it surfaces assets that appear to belong to your organization so you can review them.

A vulnerability scanner tests a list of assets you hand it and reports the flaws it finds. Attack surface management helps build that list by surfacing assets the scanner would never know to check. The two are complementary: discovery finds the asset, testing finds the flaw. In ScanTitan, a discovered asset is never scanned automatically. You review it, confirm you are authorized to test it, and only then add it to your inventory, where it can be scanned like any other asset.

There is no single right interval, because your attack surface changes whenever someone provisions a resource, connects a SaaS tool or registers a subdomain. A yearly or quarterly check leaves long gaps. Review newly discovered assets as they appear, and re-scan the assets you have approved on a schedule that matches how quickly your environment changes.

Discovery looks for assets that appear to belong to your organization, such as subdomains and related hostnames. Each one is a candidate, not a confirmed asset. Candidates are listed for review so you can approve, dismiss or assign them. Discovery does not prove ownership, so you decide what belongs in your inventory.

Shadow IT is any asset your IT team does not know it owns: an unmanaged host, a trial SaaS account wired to your domain, an API a contractor left running. It matters because you cannot patch, monitor or decommission an asset you have never logged. In ScanTitan, a newly discovered candidate waits in a review list until someone decides whether it belongs in the inventory.

Often yes, because a small business rarely has a dedicated person maintaining an asset inventory by hand, yet a forgotten subdomain is just as exploitable at a 30-person company. Discovery review is available on the Business and Consultant plans, and consultants can assign approved assets to a client.

Discovery produces candidates only. A new candidate is not approved and not scanned until you review it and confirm you are authorized to test it. Add only assets you own or have written permission to test.
