We test what your environment can actually withstand.

  • Penetration testing

  • Security assessments

  • Phishing, social engineering, and training

We test the agreed scope against defined attack scenarios. The report separates verified findings from assumptions, explains their impact, and gives technical teams a practical basis for remediation.

Services

We assess applications, networks, and infrastructure through focused technical testing and broader security reviews. We also run phishing simulations and employee training, advise on remediation, and support incident response.

  1. Training, phishing, and social engineering

    We tailor training and test scenarios to employee roles and the situations your organisation needs to address.

    • Phishing simulations
    • Social engineering assessments
    • Campaign reporting
    • Employee training
  2. Penetration testing

    We use controlled attack scenarios to determine whether weaknesses in the agreed scope can be exploited and what impact they could have.

    • Web applications
    • Internal networks
    • External infrastructure
    • Wi-Fi
    • Red teaming
  3. Security assessments

    We review configurations, internet-facing services, and selected security controls. This identifies weaknesses without making exploitation the primary objective.

    • Vulnerability assessment
    • Configuration review
    • Internet-facing services
    • Control validation
  4. Security consulting and incident response

    We help prioritise remediation and review planned changes. During an incident, we help establish its scope, contain the impact, and plan the next steps.

    • Finding prioritisation
    • Remediation planning
    • Change reviews
    • Incident response

Where to start

Start with the system, planned change, or concern that prompted the security review. From there, we can recommend what to test and how.

You need to test a specific system

Application, network, or infrastructure

Tell us what needs testing and why. It may be a new application, an infrastructure change, a customer requirement, or a routine review.

You do not know where to start

Your first security assessment

We review the critical systems, exposed services, and your main concerns. We then recommend where an initial test would provide the most useful evidence.

You are addressing employee security

Phishing, social engineering, or training

We tailor simulations to employee roles and situations they encounter at work. Training focuses on specific risks and practical responses people can use in their day-to-day work.

How we work

First, we clarify what you need to learn and how the test can be performed safely. We then conduct the assessment and review the results with you.

  1. Clarify the brief

    We confirm what needs testing, which systems are involved, when the work should take place, and which methods we may use.

  2. Conduct the test

    We assess the agreed systems and verify whether individual weaknesses can be exploited or combined into a more serious scenario.

  3. Explain the results

    We deliver the confirmed findings, explain their impact, and recommend remediation. The technical team receives the detail needed to fix them.

Team

The same people clarify the brief with you, answer technical questions, and walk you through the assessment results.

Briefly describe what needs assessing or who the training is for. We will get back to you to clarify the brief, scope, and next steps together.

Your inquiry will be sent directly to the TELA team.
