What is Qualys WAS?
Qualys’s app-security & attack-surface page — know your external footprint (CSAM/EASM), then DAST-scan the web apps & APIs on it (WAS), all on one asset inventory and one TruRisk score.
Scan-only app-sec sprawl vs WAS + attack surface — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Scan-only app-sec | Web App Scanning |
|---|---|---|
| Scope of apps | Only the apps you know about | EASM finds shadow IT & orphaned apps too |
| Surface + scan | ASM and DAST in separate tools | Surface then scan, one flow |
| Cadence | Annual point-in-time pentest | Continuous, cloud-scale DAST |
| APIs | UI-only scanner misses them | REST/SOAP/GraphQL API scanning |
| Inventory | App silo, separate from host VM | Same asset inventory as VMDR |
| Prioritisation | App-only severity ratings | One TruRisk score, app + host |
| Compliance | Scramble for PCI evidence | Audit-ready PCI/OWASP reports |
| Best fit | (varies) | App-sec + attack surface, one platform |
Qualys WAS is app-sec & attack surface — know your external footprint (CSAM/EASM), then DAST-scan the web apps & APIs on it (WAS: OWASP Top 10, injection, XSS, misconfigs), on the same asset inventory & one TruRisk score. Honest: dedicated DAST specialists (Invicti/Checkmarx/AppScan, Burp for manual pentest) go deeper on pure web-app testing; EASM leans on VMDR/WAS for testing. TechBag scopes modules/counts, adds GST & the India PCI/RBI framing.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
CSAM + EASM
CSAM keeps a full asset inventory, and EASM finds unknown internet-facing assets — shadow IT, forgotten domains, orphaned apps and APIs.
Web App & API Discovery
WAS discovers and maps the web apps and APIs on that footprint, including REST/SOAP/GraphQL and Swagger/Postman-defined APIs.
DAST Scanning
DAST scans running apps and APIs for OWASP Top 10 issues like injection and XSS, authenticated and continuously, at cloud scale.
One TruRisk Score
App and API findings join the same inventory and TruRisk score as host, cloud and OT vulnerabilities on the same asset.
One Platform, One Estate
WAS and CSAM/EASM are apps on the Enterprise TruRisk Platform, sharing inventory and data with VMDR and compliance.
One inventory of web apps and APIs from CSAM and EASM — scanned continuously by DAST and scored with the rest of the estate.
Twelve capabilities. Discover, scan, prioritise.
Qualys WAS discovers your external attack surface (CSAM/EASM) & DAST-scans the web apps and APIs on it — on one TruRisk score — the app-security & attack-surface app of the Qualys portfolio.
Full Asset Inventory (CSAM)
CSAM keeps a complete inventory with software, ports, certificates and EoL/EoS context — the base for app-sec.
External Attack Surface Mgmt (EASM)
Finds unknown internet-facing assets — shadow IT, forgotten domains, orphaned apps and APIs — attackers can see.
Web App & API Discovery
Discovers and maps the web apps and APIs on your footprint, so every endpoint is a known, tracked asset.
Dynamic App Security Testing (DAST)
Dynamically scans running apps for OWASP Top 10 issues — injection, XSS, misconfigs, exposed data — as an attacker would.
API Scanning (REST/SOAP/GraphQL)
Scans REST, SOAP, GraphQL and Swagger/OpenAPI or Postman-defined APIs, not just the web UI.
Authenticated & Deep Scanning
Authenticated and deep scans test the app behind the login, where the sensitive functions and data live.
Malware & Sensitive-Data Detection
Detects malware on web apps and flags exposed PII or cardholder data, beyond code flaws.
Continuous, Cloud-Scale Scanning
Scans continuously across hundreds or thousands of apps, catching issues as apps change rather than yearly.
TruRisk Prioritisation (App + Host)
App and API findings use the same TruRisk score as host, cloud and OT vulnerabilities on the same asset.
Same Asset Inventory as VMDR
App findings sit on the same inventory as VMDR host findings, showing an asset’s whole exposure in one place.
PCI & Compliance Reporting
Audit-ready reports for PCI-DSS (which explicitly requires web-app scanning), OWASP and ISO.
Ticketing & Remediation Workflows
Routes findings to owners via ServiceNow, Jira and no-code workflows, so flaws get fixed and closed.

Here’s what genuinely sets Qualys WAS apart (and where a specialist leads).
Surface then scan — know your external footprint, then test the apps on it
Breached apps are usually ones nobody remembered: shadow IT, forgotten microsites, orphaned staging sites, undocumented APIs. A standalone DAST tool only scans what you list. Qualys’s CSAM/EASM finds your internet-facing footprint, then WAS discovers and scans the web apps and APIs on it, continuously.
One platform, one inventory, one TruRisk score — app-sec isn't a silo
In most firms, web-app scanning sits in a separate DAST tool with its own app list and severity scale, apart from host vulnerability management. Qualys WAS findings join the same inventory and TruRisk score as VMDR, so an XSS sits next to the unpatched CVEs on its host and is prioritised with them.
Continuous, cloud-scale DAST — including the APIs, not an annual pentest
An annual pentest is a snapshot that covers a handful of apps and misses every change since. WAS runs automated DAST continuously across your whole portfolio — OWASP Top 10, injection, XSS — with authenticated scans and dedicated API scanning (OpenAPI, Postman, GraphQL). Burp still has its place for manual pentesting.
A proven, cloud-scanning pioneer — accuracy, breadth and high recommend scores
Qualys pioneered cloud vulnerability scanning in 1999, is listed on NASDAQ (QLYS) and serves >10,000 customers. WAS inherits that maturity: accurate detections and the scale to scan hundreds or thousands of apps with no infrastructure to run — often on a platform you already use for VMDR.
Built for compliance — PCI needs web-app scanning — and TechBag adds the India layer
PCI-DSS explicitly requires regular web-application scanning, and WAS produces that evidence with OWASP and ISO 27001 mapping and audit-ready reports — relevant to Indian payments, BFSI and government. Qualys quotes per app or asset in USD; TechBag scopes modules, sizes counts and invoices in INR/GST.
The honest scope
For the deepest pure DAST, Invicti, Checkmarx, AppScan and Rapid7 InsightAppSec lead; Burp is the standard for manual pentesting; and Axonius, CyCognito, Censys and Defender EASM specialise in discovery. Qualys’s edge is joining EASM and WAS on one inventory and one TruRisk score.

Quick poll — what’s driving your evaluation?
Talk to an advisor“EASM found internet-facing apps we’d forgotten we owned, and WAS scanned them, all in the same inventory.”
“An XSS on an app now sits next to the unpatched CVEs on its host. We see a server’s whole exposure in one place.”
“We moved from an annual pentest to continuous WAS across hundreds of apps and APIs, catching issues as we deploy.”
“For our PCI scope, WAS produced exactly the web-app scanning evidence our QSA wanted. TechBag framed the deployment around PCI and handled GST.”
“We keep Burp for manual pentests and rate Invicti highly, but for continuous scanning on one risk score, Qualys wins.”
“API scanning mattered most — REST, GraphQL, Swagger-defined endpoints. A UI-only scanner would have missed it.”
“Rapid7, Checkmarx and AppScan were close, but WAS uses the same inventory and TruRisk score as our VMDR.”
“Qualys quotes per app/asset in USD. TechBag scoped the counts, invoiced in INR/GST and gave us the PCI framing.”
Where everyone sits — the grids

What could this save you?
Drag the sliders (web apps & APIs; security-hour cost as loaded rate). Estimates contrast scan-only app-sec sprawl (a separate DAST tool, no attack-surface discovery so shadow IT goes untested, an app-only silo, annual pentest cadence) vs Qualys WAS (surface-then-scan, continuous cloud-scale DAST incl. APIs, one asset inventory and one TruRisk score) — the wins are fewer untested internet-facing apps, faster prioritisation, and one risk view. Illustrative — TechBag scopes your estate.

The 8 questions to ask every vendor
Take this into your next vendor call — including ours.
Do you know every internet-facing app you own? CSAM/EASM finds shadow IT and orphaned apps; WAS scans them.
Are you only scanning the apps you already know about? Qualys joins attack-surface discovery with DAST scanning in one flow.
Are your APIs tested? WAS scans REST/SOAP/GraphQL and Swagger/Postman-defined APIs — not just the web UI.
Still doing an annual pentest? WAS runs continuous, cloud-scale DAST across your whole portfolio as apps change.
Is app-sec a silo? WAS shares the SAME asset inventory and ONE TruRisk score as your host/infrastructure risk.
PCI in scope? PCI-DSS explicitly requires web-app scanning — WAS produces the audit-ready evidence (plus OWASP/ISO).
Weighing Invicti, Rapid7, Checkmarx, Burp or AppScan? They go deeper on pure DAST; Qualys’s edge is integration.
Qualys prices per app/asset by quote in USD — TechBag scopes modules/counts, adds INR/GST and the PCI/RBI/CERT-In framing.
