Social Engineering Providers

Social engineering testing evaluates the human element of your organisation's security posture by simulating real-world manipulation techniques used by attackers. This includes phishing campaigns (email-based attacks with malicious links or attachments), vishing (voice-based social engineering via phone calls), smishing (SMS-based attacks), pretexting (creating convincing scenarios to extract information), and physical social engineering (tailgating, impersonation, and badge cloning).

Professional social engineering assessments are carefully designed to test employee awareness and response without causing undue distress. Results help organisations understand their vulnerability to human-targeted attacks, which are involved in the majority of successful breaches. Social engineering testing is particularly valuable when combined with security awareness training programmes, providing a measurable baseline and evidence of improvement over time.

Many compliance frameworks including PCI DSS, NIST CSF, and ISO 27001 recommend or require social engineering testing as part of a comprehensive security programme. Testing should be conducted under strict rules of engagement with management approval and ethical guidelines.

Social Engineering FAQs

Will employees know they are being tested?+

Typically no - the test is more effective when employees are unaware. However, management and HR should be informed, and organisations should have a supportive policy that focuses on education rather than punishment.

What metrics do social engineering tests provide?+

Key metrics include click rates, credential submission rates, reporting rates, and time to report. These help measure security awareness and track improvement over time.

Is social engineering testing ethical?+

Yes, when conducted professionally with management authorisation, clear rules of engagement, and a focus on organisational improvement rather than targeting individuals. Reputable providers follow strict ethical guidelines.
