2026 External Threat & Attack Surface Engine

Continuous External Vulnerability Scanner

Stop relying on static monthly pen-tests. bspeka provides automated 24/7 external vulnerability scanning across your domains, APIs, and cloud perimeters—detecting exposed ports, dangerous CORS policies, SSL flaws, and dangling DNS before attackers strike.

  • 100% Agentless & Zero Config: Discover and scan assets from the outside without touching internal servers.
  • Multi-Vector Security Engines: Full audit of Open Ports, CORS, SSL/TLS, DNS leaks, and Security Headers.
  • Continuous CVE & Shadow IT Discovery: Immediately flags newly published endpoints, forgotten test servers, and exposed services.
  • Audit-Ready Compliance: Built to meet NIS2 Directive Article 21, SOC 2 Type II, and ISO 27001 requirements.
bspeka-scanner-daemon // active_scan
Critical Risk dev-api.acme-corp.com
Subdomain Takeover / Dangling CNAME
CNAME points to unclaimed AWS S3 bucket. Attacker can claim bucket and execute arbitrary code.
High Risk staging-db.acme-corp.com:5432
Publicly Exposed PostgreSQL Port
Database port 5432 is publicly reachable from the internet without IP whitelisting.
Medium Risk auth.acme-corp.com/v1/user
Insecure CORS Credential Reflection
Access-Control-Allow-Origin dynamically reflects arbitrary origins with Allow-Credentials: true.
Low Risk portal.acme-corp.com
Missing Content Security Policy (CSP)
Strict CSP header missing; increases susceptibility to cross-site scripting (XSS) vectors.

Six Specialized Vulnerability Scanning Engines

Modern breaches rarely exploit zero-day hardware flaws; they exploit simple, overlooked external misconfigurations. bspeka audits your perimeter through 6 dedicated scanners.

Open Port & Service Banner Scanner

Detects publicly exposed administrative services, unauthenticated databases, and vulnerable daemons across thousands of network ports before hackers discover them on Shodan or Censys.

  • Scans databases: Postgres 5432, MySQL 3306, Redis 6379
  • Audits remote admin: SSH 22, RDP 3389, Elastic 9200
  • Extracts service banners for unpatched CVE fingerprinting

CORS Misconfiguration Scanner

Cross-Origin Resource Sharing vulnerabilities allow malicious third-party websites to siphon private session tokens, PII, and sensitive user data from your internal and customer APIs.

  • Tests arbitrary origin reflection with Allow-Credentials
  • Detects wildcard * origins on authenticated endpoints
  • Validates null origin trust relationships and regex bypasses

SSL / TLS & Cipher Strength Scanner

Audits SSL/TLS certificates and encryption suites across all domains and subdomains to prevent certificate outages, man-in-the-middle attacks, and compliance violations.

  • Alerts 30, 14, and 7 days prior to SSL expiration
  • Detects deprecated protocols: TLS 1.0, TLS 1.1, SSLv3
  • Verifies SAN certificates and trust chain validity

HTTP Security Header Auditor

Evaluates web defense layers that safeguard browsers against Clickjacking, Cross-Site Scripting (XSS), MIME-confusion attacks, and cleartext downgrades.

  • Enforces Content-Security-Policy (CSP) integrity
  • Checks Strict-Transport-Security (HSTS) preload eligibility
  • Audits X-Frame-Options & Referrer-Policy

DNS Misconfiguration & Email Spoofing

Scans domain zone records for dangerous DNS anomalies, broken MX delegations, missing anti-phishing safeguards, and misrouted nameservers.

  • Audits SPF, DKIM, and DMARC reject policies
  • Detects lame nameservers and vulnerable zone transfers (AXFR)
  • Verifies DNSSEC implementation status

Subdomain Takeover & Zombie Cloud Scanner

Continuously tracks CNAME records pointing to decommissioned AWS S3 buckets, Azure App Services, GitHub Pages, Fastly, and 40+ cloud providers before hijackers claim them.

  • Active signature matching for 40+ SaaS/cloud providers
  • Instant Slack, Email, and Webhook notifications upon detection
  • Provides 1-click DNS record deletion instructions

Why Legacy Scanners Fail Modern Cloud Teams

Traditional vulnerability scanners were built 20 years ago for static data centers with fixed IP ranges. Today's dynamic cloud architectures demand modern Attack Surface Management (EASM).

Capability bspeka Continuous EASM Legacy Scanners (Nessus/Qualys) Annual Penetration Tests
Asset Discovery ✓ 100% Automated Subdomain & Cloud Recon ~ Requires manual target IP lists ✗ Static snapshot of agreed scope
Scan Frequency ✓ Continuous 24/7 or Daily ~ Scheduled monthly or quarterly ✗ Once or twice per year
Agent Requirement ✓ Zero Agents (100% External Perspective) ✗ Heavy internal agent or credential setup ✓ Zero Agents
Dangling DNS / Takeover ✓ Specialized 40+ Cloud Provider Engine ✗ Ignored or very superficial ~ Caught only if tested manually
Alert Latency ✓ 5-15 Minutes ~ 24-48 Hours (huge scan windows) ✗ 2-4 Weeks after audit completes
Pricing for SMBs & Scaleups ✓ Transparent €79/mo (Flat, unlimited assets) ✗ $5,000–$25,000/year + Per-IP fees ✗ $10,000–$40,000 per engagement

How bspeka Vulnerability Scanning Works

Set up in 2 minutes. No credit card required. Immediate visibility into your external attack perimeter.

Step 1

Enter Your Apex Domain

Provide your company domain (e.g. acme.com). bspeka instantly kicks off multi-source OSINT discovery to uncover subdomains, cloud IPs, and DNS records.

Step 2

Deep Multi-Vector Scanning

Automated daemons test every discovered asset for open database ports, weak SSL ciphers, dangerous CORS configurations, and missing security headers.

Step 3

Prioritized Threat Ranking

Cut through alert fatigue. Issues are scored by true exploitability and blast radius so your engineering team fixes critical vulnerabilities first.

Step 4

Remediation & Continuous Watch

Receive step-by-step remediation snippets. bspeka verifies fixes automatically and monitors your infrastructure 24/7 for newly introduced regressions.

Frequently Asked Questions

Everything you need to know about external vulnerability scanning and attack surface security.

What is an external vulnerability scanner?
An external vulnerability scanner inspects your organization's digital perimeter exactly as an external attacker would. Without requiring inside credentials or server agents, it analyzes publicly accessible web applications, subdomains, cloud buckets, and network ports to identify unpatched software, misconfigurations, and weak cryptographic settings.
Why is automated vulnerability scanning essential for NIS2 and SOC 2?
Regulatory frameworks like the European NIS2 Directive (Article 21) and compliance standards such as SOC 2 (Trust Services Criteria CC6.8 and CC7.1) mandate that organizations actively manage cybersecurity risk across their supply chain and digital assets. Continuous vulnerability monitoring provides verifiable audit logs that prove your external attack surface is consistently secured.
Will bspeka's scanner slow down or disrupt our production services?
No. bspeka utilizes lightweight, non-intrusive protocol probes and safe HTTP requests designed specifically to measure server response, banner info, and header configurations without causing denial of service or application degradation.
How does bspeka handle new subdomains created by developers?
bspeka continuously watches Certificate Transparency (CT) logs and DNS updates. The moment a developer registers a new subdomain or spins up a staging environment, bspeka automatically discovers the host and runs the full vulnerability scanning suite without manual intervention.
What happens when a vulnerability is found?
You receive an instant alert via your preferred channel (Email, Slack, or Webhook). Each alert includes the affected endpoint, severity level, reproduction proof, and precise copy-paste remediation steps for your DevOps and security teams.
