Web Tampering Detection & Security System

Web Tampering Security System

Detect website changes and anomalies in real time to support safer service operations.

Advanced web crawling analyzes page state in real time, detects tampering, outages, and errors, and alerts security teams immediately.

Process

Detection workflow

  1. 01

    Collect

    Agentless collection pulls page source without installing agents, so the web server stays light.

  2. 02

    Analyze

    In-house HASH, DOM, keyword, and AI/ML analysis inspect the page for tampering.

  3. 03

    Detect events

    Defined events such as outage, delay, error, defacement, and dead links are matched against detection rules.

  4. 04

    Alert and respond

    Security teams are notified immediately so they can verify status and act quickly.

Detection Events

Events WebTSS detects

  • Outage

    Flags refused connections from server downtime, firewall or proxy blocks, DNS failures, and TLS/SSL certificate errors.

  • Delay

    Alerts when server load or traffic slows responses, or when a reply exceeds the crawler timeout.

  • Error

    Records 400 and 500 HTTP response codes after a page request, grouped by status code.

  • Defacement

    Checks live tampering on monitored pages with HASH, DOM, keyword, and AI/ML analysis.

  • Detection rules

    Applies signature-based rules with registered keywords and regular expressions (regex).

  • Dead links

    Finds page links that were removed or cannot open because of filters, firewalls, or network issues.

  • optional

    External links

    Extracts unapproved or inbound external links and compares them against a whitelist.

  • optional

    Malware

    Scans registered domains and URIs through trusted APIs for malicious page or domain events.

Key Features

Key features

  • Defacement analysis

    Keyword analysis combined with AI for more precise tampering detection.

  • Stronger outage analysis

    Retries plus a second check through an external proxy raise confidence and cut false positives.

  • Malicious activity detection

    Detects malicious code, files, and domain events.

  • Dead and external link detection

    Finds unreachable links on the page and external links that are not allowed.

  • Granular policy control

    Apply defacement, delay, and detection-rule policies separately by organization, domain, and URI.

  • Real-time monitoring

    Live CPU, memory, database, and disk status, plus event collection from a lightweight high-performance crawler.

  • GS Certification Grade 1

    Trusted software that passed fitness checks for performance and security against ISO international standards.

  • Dynamic browsing support

    Supports dynamic browsing across operating environments and multiple browsers, including Chrome, Whale, and Edge.

Use cases

Where teams use it

For public-sector and enterprise teams that cannot afford to miss tampering or outage signals on live sites.

  • Public portals

    Monitor many citizen-facing pages in one place for outages, HTTP errors, and defacement, then alert owners immediately.

  • Corporate and financial sites

    Watch flagship homepages and key landings with HASH, DOM, and keyword analysis, and review HTML diffs when content changes.

  • Many URLs and owners

    Apply defacement, delay, and detection-rule policies per organization, domain, and URI so large estates stay consistent.

  • Smaller teams on SaaS

    Use the subscription service for 24/7 monitoring and email or alert notifications without an on-premises build.

Service

Service options

On-premises deployment for organizations that run many sites, and a subscription service for teams that prefer SaaS.

On-premises
  • WebTSS-Express

    Best for sites with 50 URLs or fewer

    Crawls and analyzes every event on a single all-in-one server.

  • WebTSS-SE

    Best for sites with 200 URLs or fewer

    Two servers: a collector plus an analyzer.

  • WebTSS-EE

    Best for sites with 200 URLs or more

    N collector servers plus an analyzer.

Subscription (SaaS)

A subscription for teams with fewer sites, or that do not want on-premises infrastructure. Choose monthly or annual billing, and cancel at any time.

  • Real-time monitoring

    Monitor around the clock with DL-WebTSS and receive events by email, alert, and more.

  • Practical pricing

    Companies and individuals with fewer sites can use the same service as on-premises, without an upfront build cost.

  • Ongoing updates

    Periodic performance and feature updates are included. Major updates are scoped separately.

  • Monthly reports

    Monthly reports show event volume and trends at a glance.
