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.
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
CyberSecurity Asset Management (CSAM) builds a full, always-current asset inventory; External Attack Surface Management (EASM) discovers the internet-facing, previously-unknown assets — shadow IT, forgotten domains, orphaned web apps and APIs — that attackers can see from outside. You can't scan what you don't know you own. Know the surface first.
WAS automatically discovers and catalogues the web applications and APIs on that footprint — crawling and mapping them (including REST/SOAP/GraphQL, Swagger/Postman-defined APIs) — so every app and endpoint is a known, tracked asset, not a blind spot. Complete app catalogue. Nothing untested because it was unseen.
Dynamic application security testing (DAST) scans running apps and APIs for OWASP Top 10 issues — injection, cross-site scripting (XSS), security misconfigurations, exposed sensitive data, authentication flaws and more — with authenticated scanning, at cloud scale, on a continuous cadence. Real vulnerabilities, found continuously — not a once-a-year pentest.
Every app and API finding rolls into the SAME asset inventory and the SAME TruRisk score as your host, cloud and OT vulnerabilities — so an app flaw sits next to the host flaws on the same asset, prioritised in one business-aligned risk language. Not a siloed app-sec report — one risk picture.
WAS and CSAM/EASM are apps on the Enterprise TruRisk Platform — the same inventory, agents and data that power VMDR, cloud security and compliance — so app-security and attack surface aren't a separate point tool but part of one unified estate. One platform, one risk language. App-sec, unified.
One agent on every machine, one console over all of them — modules attach without a second operational world.
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 portfolio, and paired with the human firewall.
CyberSecurity Asset Management builds a complete, always-current inventory of every asset — with rich context (software, ports, certificates, EoL/EoS) — as the foundation the whole app-security and attack-surface picture is built on. You can't scan what you can't see. Complete, current inventory.
Discover internet-facing, previously-unknown assets — shadow IT, forgotten domains, orphaned web apps and APIs — so your inventory includes exactly what attackers can see from outside. Find your footprint before they do. No blind spots outside.
Automatically discover and catalogue the web apps and APIs on your footprint — crawling and mapping them — so every application and endpoint becomes a known, tracked asset. Nothing untested because it was unseen. Every app, catalogued.
Scan running web apps for real, exploitable vulnerabilities — OWASP Top 10, injection, cross-site scripting (XSS), security misconfigurations, exposed sensitive data — dynamically, as an attacker would. Real running-app testing. Find what's actually exploitable.
Scan APIs — REST, SOAP, GraphQL, and Swagger/OpenAPI or Postman-defined — for the vulnerabilities that increasingly live in the API layer, not just the web UI. APIs are the new attack surface. Scan them too.
Run authenticated scans (logging in as a real user) and progressive/deep scans — so you test the app behind the login, where the most sensitive functionality and data live, not just the public surface. Test behind the login. Where the risk really is.
Detect malware on your web apps and flag exposed sensitive data (PII, cardholder data) — so scanning covers not just code flaws but content-level exposure and integrity risks. Beyond code flaws — content risk too. Catch exposure and malware.
Scan continuously and at cloud scale across hundreds or thousands of apps — not a once-a-year manual pentest — so new vulnerabilities are caught as apps change and deploy. Always-on app-sec. Not an annual snapshot.
Roll every app and API finding into the SAME TruRisk score as your host, cloud and OT vulnerabilities — so an app flaw is prioritised next to the host flaws on the same asset, in one business-aligned risk language. One score, app and infrastructure together.
App findings live on the SAME asset inventory as VMDR host findings — so you see the whole exposure of an asset (its host vulns AND its web-app vulns) in one place, not two disconnected tools. One inventory, whole-asset view. Not a silo.
Produce the web-app scanning evidence auditors want — PCI-DSS (which explicitly requires web-app scanning), OWASP, ISO — with audit-ready reports mapped to the mandates. Scanning that also proves compliance. Audit-ready by design.
Route app and API findings to owners with ITSM/ticketing integration (ServiceNow, Jira) and no-code workflows — so a discovered flaw flows to whoever fixes it and gets closed. From finding to fixed, orchestrated. Not just a report.

Book a guided demo →Here’s what genuinely sets Qualys WAS apart (and where a specialist leads).
The single biggest reason to choose Qualys here is that it joins the two halves of application-security risk that usually live in separate tools: knowing your external attack surface (CSAM/EASM) AND scanning the web apps and APIs on it (WAS) — in one flow, one inventory. The problem it solves: most app-security programmes scan the apps they KNOW about — but the apps that get breached are usually the ones nobody remembered they owned: shadow IT, forgotten marketing microsites, orphaned staging environments, undocumented APIs. You can't scan what you don't know you have, and a standalone DAST tool has no idea what your real external footprint is. What Qualys provides: CyberSecurity Asset Management (CSAM) with External Attack Surface Management (EASM) continuously discovers your internet-facing and previously-unknown assets — the footprint an attacker actually sees — and then WAS automatically discovers and DAST-scans the web apps and APIs on it (OWASP Top 10, injection, XSS, misconfigs, exposed data), authenticated and at cloud scale, continuously. Discover the surface, then scan it — so nothing goes untested because it was unseen. Why it matters: closing the gap between 'unknown asset' and 'scanned asset' is where real app-security risk is reduced — you find and test the forgotten, internet-facing apps before an attacker does, instead of only scanning the ones already in a spreadsheet. The value: Qualys joins EASM and WAS — know your external footprint, then scan the web apps and APIs on it — so shadow IT and orphaned apps get discovered AND tested. For real app-attack-surface reduction, this matters. TechBag helps organisations run surface-then-scan with Qualys.
A defining strength of Qualys WAS is that it isn't a standalone point tool — it's an app on the Enterprise TruRisk Platform, sharing the SAME asset inventory and the SAME TruRisk score as VMDR, cloud security and compliance — so app-security risk is prioritised in one language, next to everything else. The problem it solves: most organisations run web-app scanning in a separate DAST tool, with its own console, its own list of apps and its own severity ratings — disconnected from the host/infrastructure vulnerability programme. The result is a silo: an app flaw and the host flaws on the SAME server live in two different tools, ranked two different ways, and nobody sees the whole exposure of that asset. What Qualys provides: every WAS app/API finding rolls into the same asset inventory as your VMDR host findings and into ONE TruRisk score — correlated with real-world threat intelligence and asset criticality — so an XSS on an app sits next to the unpatched CVEs on its host, on the same asset, prioritised together. You see the whole exposure of an asset in one place and report app + infrastructure risk as one number. Why it matters: unified prioritisation means your limited remediation capacity goes to the truly dangerous findings across app AND infrastructure, not to whichever tool shouts loudest — and leadership gets one risk picture, not two disconnected reports. The value: WAS shares one inventory and one TruRisk score with the rest of Qualys — so app-sec is prioritised next to host risk on the same asset, not in a silo. For unified risk, this matters. TechBag helps organisations consolidate app-sec onto the Qualys platform.
A core strength of WAS is that it scans web apps AND APIs continuously and at cloud scale — across hundreds or thousands of apps — instead of relying on a once-a-year manual penetration test that's out of date the moment the next deploy ships. The problem it solves: many organisations still 'do app-sec' as an annual pentest — a point-in-time snapshot that misses everything that changed since, and can only cover a handful of apps by hand. Meanwhile apps deploy weekly and the attack surface has shifted to APIs (REST, SOAP, GraphQL) that a UI-only scanner never touches. What WAS provides: automated dynamic application security testing (DAST) that discovers and scans running web apps for OWASP Top 10 issues — injection, cross-site scripting (XSS), misconfigurations, exposed sensitive data, authentication flaws — WITH authenticated scanning (testing behind the login where the sensitive functionality is) and dedicated API scanning (Swagger/OpenAPI, Postman, GraphQL). It runs continuously and scales in the cloud to your whole app portfolio. Why it matters: continuous, broad, API-aware scanning catches vulnerabilities as apps change — not months later in an annual report — and covers the whole portfolio and the API layer that manual pentests can't reach at scale. Manual pentesting still has its place (and Burp is the tool for that); automated continuous DAST is what covers everything, always. The value: WAS is continuous, cloud-scale DAST across web apps AND APIs — authenticated, OWASP-aware — so your whole portfolio is tested continuously, not once a year. For scalable app-sec, this matters. TechBag helps organisations move from annual pentest to continuous WAS.
Qualys WAS is chosen with confidence because Qualys is a proven pioneer of cloud-delivered security scanning (since 1999) with a deep detection library, huge breadth, and consistently high 'willing to recommend' scores. The track record: Qualys effectively invented cloud-based vulnerability scanning — it's been doing this at scale for 25+ years, is public (NASDAQ: QLYS), serves >10,000 customers including much of the Fortune 100, and processes trillions of security data points. WAS inherits that heritage: mature detections, scale, and the reliability of a cloud platform you don't have to run yourself. What that means for you: accurate app and API detections you can trust, enormous scale (scan hundreds or thousands of apps without standing up scanning infrastructure), and the operational simplicity of one cloud platform. And Qualys consistently earns high recommend/renewal scores — customers who standardise on the platform tend to keep it and add more apps (VMDR, TotalCloud, compliance) on the same foundation. Why it matters: in scanning, accuracy and scale are everything — you're trusting the tool to tell you the truth about your app risk, across your whole portfolio, continuously. Qualys's long pedigree and platform scale make WAS a low-risk, proven choice — especially when it's part of a platform you may already run for VMDR. The value: Qualys is a proven cloud-scanning pioneer — accurate, broad, cloud-scale, with high recommend scores — and WAS rides that heritage. For a trustworthy app-sec foundation, this matters. TechBag helps organisations deploy proven WAS.
Qualys WAS (and the broader Qualys platform) is deeply aligned with compliance — and web-app scanning is EXPLICITLY required by PCI-DSS — which for Indian enterprises, especially BFSI, payments and government, is a major driver; TechBag adds the local scoping, licensing and INR/GST support plus the India compliance framing. The compliance fit: PCI-DSS requires organisations that handle cardholder data to perform regular web-application vulnerability scanning — WAS is built to produce exactly that evidence, alongside OWASP and ISO 27001 mapping and audit-ready reports. Continuous scanning, misconfiguration detection and clean reporting are exactly what QSAs, auditors and regulators want. Why this matters in India: Indian regulators are raising the bar — RBI cyber-resilience norms, CERT-In directives (incident reporting, log retention), SEBI, and PCI-DSS for anyone in the payments chain. WAS's continuous web-app/API scanning and audit-ready reporting map well to these — a strong fit for Indian BFSI, payments, government/PSU and IT/ITES. (Qualys also has major R&D in Pune — India is central to the company.) Where TechBag adds value: Qualys sells largely through channel partners and prices per-app/per-asset by quote, in USD — so TechBag adds the local layer: scoping which modules you need (WAS, CSAM/EASM, and how they sit with VMDR), sizing the app and asset counts, INR/GST invoicing, and framing the deployment against India's compliance requirements (PCI especially, plus RBI/CERT-In) and helping verify India data-residency where needed. The value: Qualys WAS is built for compliance — PCI explicitly needs web-app scanning — and TechBag adds the India layer: module scoping, INR/GST, and the PCI/RBI/CERT-In framing. TechBag supplies it with local, compliance-aware support. TechBag provides Qualys, made local for India.
Qualys Web App & API Scanning is the application-security and attack-surface page of the Qualys Enterprise TruRisk Platform — it joins CyberSecurity Asset Management with External Attack Surface Management (CSAM/EASM: know your external footprint) with Web Application Scanning (WAS: DAST-scan the apps and APIs on it), all on the same asset inventory and one TruRisk score, from a proven cloud-scanning pioneer (founded 1999; NASDAQ: QLYS; >10,000 customers). The honest framing — strengths, and where rivals lead: Qualys's strengths here are surface-then-scan (EASM + WAS joined), integration with the same inventory and one TruRisk score across app AND infrastructure, continuous cloud-scale DAST including APIs, and the reliability of a proven platform. The competitive landscape is strong and real. For pure web-app testing depth, the DAST specialists lead: Invicti (Netsparker/Acunetix) is known for proof-based scanning that verifies exploitability to cut false positives; PortSwigger's Burp Suite is the de-facto standard for MANUAL penetration testing (Burp is a pentester's tool, not a continuous-scanning platform); Rapid7 InsightAppSec and Checkmarx DAST and HCL AppScan are strong, mature DAST tools — several with SAST/IAST siblings for a fuller app-sec suite. So for the deepest pure DAST, or for hands-on manual pentesting, a specialist may go deeper than Qualys. And an honest caveat on the EASM half: Qualys's attack-surface management leans on VMDR/WAS for the actual testing rather than doing deep unauthenticated testing of its own, and dedicated EASM/ASM players — Axonius, CyCognito, Censys, Microsoft Defender EASM — specialise in that discovery lane. Qualys's edge is NOT being the single deepest DAST or the single deepest EASM — it's joining attack-surface discovery and app/API scanning WITH the same asset inventory and one TruRisk score on one platform, so app-sec isn't a silo. So the honest positioning: for web-app and API scanning integrated with your attack surface and one risk score across your whole estate — from a proven, compliance-aligned pioneer — Qualys WAS is a leading platform choice; for the deepest pure DAST look at Invicti/Checkmarx/AppScan, for manual pentesting Burp, and for dedicated EASM Axonius/CyCognito/Censys/Defender EASM. TechBag scopes Qualys honestly — the right modules and app/asset sizing, comparing vs the DAST specialists, with the India compliance framing (PCI/RBI/CERT-In) and GST invoicing.
Which modules — WAS (web-app & API scanning), CSAM/EASM (attack surface), and how they sit with VMDR? — and the app/asset counts (Qualys prices per app/asset). TechBag scopes it, sizes it, and frames it against your compliance mandates (PCI especially, plus RBI/CERT-In).
Turn on CSAM/EASM to build the asset inventory and discover your internet-facing, previously-unknown assets — shadow IT, forgotten domains, orphaned apps and APIs — so you know exactly what an attacker sees. Know the footprint first.
Catalogue and DAST-scan the web apps and APIs on that footprint — OWASP Top 10, injection, XSS, misconfigs, exposed data — authenticated and continuously, at cloud scale. Move from annual pentest to always-on scanning.
Roll every finding into one TruRisk score alongside host risk on the same asset, route fixes to owners via ITSM, and produce audit-ready PCI/OWASP reports. TechBag supports you locally (GST).

“Surface-then-scan is the point. EASM found internet-facing apps we'd genuinely forgotten we owned, and WAS scanned them — all in the same inventory. That's the shadow-IT gap most tools miss.”
“The killer feature is one TruRisk score. An XSS on an app now sits next to the unpatched CVEs on its host, on the same asset. We finally see the whole exposure of a server in one place, not two tools.”
“We moved from an annual pentest to continuous WAS across hundreds of apps, APIs included. It scales in the cloud and we catch issues as we deploy, not months later in a report.”
“For our PCI scope, WAS produced exactly the web-app scanning evidence our QSA wanted. TechBag framed the deployment around PCI and handled GST.”
“Honest: for the very deepest pure DAST we still keep Burp for manual pentesting and rate Invicti's proof-based scanning highly. But for continuous scanning integrated with our whole estate and one risk score, Qualys wins. TechBag gave us that honest comparison.”
“API scanning mattered most to us — REST and GraphQL, Swagger-defined endpoints. That's where our real attack surface moved, and a UI-only scanner would have missed it.”
“We compared Rapid7 InsightAppSec, Checkmarx and AppScan head-to-head. Qualys won for us because WAS uses the SAME inventory and TruRisk score as our existing VMDR — no new silo. TechBag helped us weigh them honestly.”
“Qualys prices per app/asset by quote, in USD — TechBag scoped the WAS and CSAM/EASM counts, added INR/GST invoicing and local support, and gave us the PCI framing. A proven platform, made local.”

Drag the sliders (web apps & APIs; open app vulnerabilities; 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.
Loaded cost = salary + overheads per productive hour. Illustrative only — your TechBag quote models actual device counts and modules.
Qualys WAS prices PER WEB APP (a pool of app licences), and CSAM/EASM PER ASSET — annual subscription, modular — quote-only (no public list; sold via channel, in USD).
