Why Network Services Security Matters?
Network services are critical gateways to your infrastructure
Network services like VPN, mail, and DNS are often exposed to the internet, making them prime targets for attackers seeking initial access to your network.
Identity services control access to your entire infrastructure. A vulnerability in LDAP, RADIUS, or SSO can compromise all connected systems.
Mail servers without proper SPF, DKIM, and DMARC configuration allow attackers to spoof your domain for phishing attacks against employees and customers.
DNS is fundamental to all network communication. DNS hijacking or poisoning can redirect users to malicious sites or intercept sensitive data.

Our Process
Our structured approach to network services security assessment
Identify all network services, their versions, configurations, and exposed endpoints through passive and active reconnaissance.
Deep dive into protocol implementations, encryption configurations, and authentication mechanisms to identify weaknesses.
Active testing of identified vulnerabilities including spoofing, injection, bypass attempts, and exploitation of known CVEs.
Comprehensive report with prioritized findings, protocol-specific remediation guidance, and free retesting to verify fixes.

Frequently Asked Questions
We test all major network services including: VPN (IPSec, OpenVPN, WireGuard, SSL VPN), Mail servers (SMTP, IMAP, POP3, Exchange), DNS (authoritative and recursive), and Identity services (LDAP, Active Directory, RADIUS, SSO/SAML, OAuth/OIDC).
VPN assessment includes: encryption protocol analysis (IKE, IPSec, TLS), authentication mechanism review, certificate validation, split tunneling analysis, client security evaluation, key exchange testing, and configuration review against best practices.
We test: SPF, DKIM, DMARC configuration and enforcement, open relay vulnerabilities, TLS encryption (STARTTLS, implicit TLS), authentication security, email header injection, attachment handling, and spam filter bypass techniques.
We test for: zone transfer vulnerabilities (AXFR/IXFR), DNS cache poisoning, DNSSEC implementation and validation, DNS amplification for DDoS, recursive resolver security, DNS rebinding attacks, subdomain takeover, and DNS tunneling detection.
Yes, our identity services assessment covers: LDAP injection, anonymous bind testing, password policy analysis, Kerberos security (Kerberoasting, AS-REP roasting), NTLM relay attacks, GPO security, trust relationships, and privileged account exposure.
Yes, we assess SSO/SAML security including: signature validation bypass, XML injection, assertion replay, token security for OAuth/OIDC, redirect URI validation, scope abuse, and client secret exposure.
We use specialized tools including: testssl.sh for TLS analysis, Nmap for service enumeration, dnsrecon/dnsenum for DNS testing, Responder/Impacket for identity services, custom scripts for protocol testing, and vendor-specific tools for VPN assessment.
Timeline depends on scope: Single service (VPN or DNS) takes 1-2 weeks. Comprehensive assessment covering all network services typically takes 2-4 weeks. Large environments with multiple service instances may require 4-6 weeks.
You receive: Executive Summary for management, Protocol Analysis Report with encryption and configuration findings, Technical Report with detailed vulnerabilities and CVSS scores, Remediation Guide with service-specific recommendations, and free retesting.
Cost depends on: number of services to test, complexity (single vs. high-availability deployments), depth of testing required, and compliance requirements. Contact us for a free consultation and customized quote.
