What is Attack Simulation?
Attack simulation (or red teaming) is a threat-led, adversarial security testing method that simulates real-world cyber attacks.
It is goal-driven and aims to breach your defences using tactics, techniques and procedures employed by real threat actors to closely mirror a persistent attack against your cyber defences and security team.
Red Teaming vs. Penetration Testing
Red teaming is scenario-driven, simulating real-world cyber-attacks to test your organisation's overall security posture, including people, processes, and technology.
Penetration testing is vulnerability-driven, focusing on identifying and exploiting flaws in specific systems.

Our Services
We offer an array of attack simulation services designed to challenge your defences and strengthen your security posture.
Red Team Engagement
A classic full end-to-end engagement to test and improve your defences.
Utilises evasion techniques and covert delivery to evaluate detection capabilities, identify security gaps and support blue teams in handling serious events.
Threat-Led Testing
Structured, intelligence-driven assessment that simulates realistic cyber-attacks based on current threat intelligence.
Simulates attacks from adversaries most likely to target your organisation and is tailored to your specific threat landscape, sector, and security posture.
Assumed Breach Assessment
Simulates a scenario where an attacker already has internal access.
Starts from a point of compromise, such as domain user access, valid credentials, or network foothold, to evaluate how your organisation detects, responds to, and contains internal threats.
Purple Team
A collaborative security testing approach where offensive (Red Team) and defensive (Blue Team) teams work together in real-time to test, detect, and improve your organisation’s ability to identify and respond to simulated cyber threats.
Continual Threat Service
Proactive, ongoing monitoring of your organisation's attack surface to ensure you stay ahead of potential adversaries.
Delivers persistent, targeted attacks using real-time intelligence to help safeguard your business while offering comprehensive, ongoing support.
EDR and XDR Evaluation
Evaluates the effectiveness of your endpoint detection and response systems against threats ranging from commodity malware to custom attacks, while providing insights into the configuration and maintenance of your security tools.
How we work
This represents a standard red team workflow. Services such as Threat-Led Testing, regulatory threat simulations, or other engagements with dedicated threat intelligence providers may use a modified workflow aligned with specific frameworks and your organisation's needs.
A fact-finding conversation to understand your needs and objectives
We generate a custom proposal containing costing information and a detailed engagement plan.
Once you accept the proposal, a team will be assigned and the engagement will be scheduled.
A scoping workshop is held to define boundaries and objectives and to fully man out all aspects of the engagement before launch.
We will execute the engagement according to the agreed plan and maintain constant communication with trusted parties.
A post-assessment workshop to discuss findings and recommendations, and provide training to your defensive teams.
The team will remain available to offer support and answer any questions you may have after the engagement.

“I’ve taken WorkNest into every organisation that I’ve worked with. I’ve introduced them to many teams and many colleagues and referred them with absolute pleasure because I genuinely trust in the service that we get.”
Joanne Beaver
Operations Director, Beaverfit
"We’ve always been very impressed with the cyber security services WorkNest provide us. Their professional approach, knowledge and flexibility have ensured they have become a key trusted partner in our supply chain."
Nick Fryer
Paymentsense - Europe largest merchant service provider, CTO
“We moved our legal support to WorkNest having previously used a time and line law firm. It was important, though, that an all-inclusive fee structure did not come at the expense of quality. Thankfully we’ve been delighted with the service we’ve received from WorkNest"
Chief Executive
Waverley Care
"WorkNest supported us with a detailed application penetration test and forensic analysis on one of our key payment-related systems. Their consultants quickly identified underlying vulnerabilities and provided clear insight into how these issues could be addressed."

Attack Simulation FAQs
A typical red team engagement involves three core groups:
Control Group – Trusted representatives from your organisation who oversee and coordinate the engagement.
Red Team – The offensive team responsible for planning and executing realistic, threat-led attack simulations.
Blue Team – Your organisation’s internal security team or third-party defenders tasked with detecting, responding to, and mitigating threats (often unaware of the exercise in advance).
In regulated frameworks like DORA, TIBER-EU, or STAR, additional participants may include regulatory bodies, Threat Intelligence providers, and independent regulating bodies to ensure compliance and realism.
We actively encourage collaboration with in-house blue teams. Coordinated red team exercises are excellent for validating existing security controls and uncovering real-world attack paths that could lead to compromise. For organisations focused on improving detection and response, we also offer fully collaborative purple team engagements.
Red teaming is ideal for organisations with mature security controls and regular penetration testing. However, businesses at any stage can benefit from it. We can assess your current security posture and recommend the most effective approach based on your goals and requirements.
Duration depends on scope, objectives and organisational maturity. A typical non-regulated red team engagement lasts 4 to 12 weeks, with options like assumed breach to reduce complexity and timelines. For regulated frameworks such as TIBER, DORA, and STAR, we follow defined phases and timelines spanning multiple months, with active testing typically around 12 weeks, varying by framework and scope.
Effective preparation starts with clear planning. Defining learning objectives, desired outcomes, and critical systems tailors realistic attack scenarios. The more clarity you give upfront, the more value and insight you gain.
WorkNest Secure is CREST STAR-accredited, with certified CCRTS team members and a structured team of Leads and Operators. We deliver engagements under TIBER-EU, DORA, and STAR frameworks, ensuring compliance with industry and regulatory standards.
Yes. We align engagements with your risk profile, industry-specific threats, and compliance needs. Whether simulating a nation-state threat, meeting DORA regulations, or addressing insider risks, we’ll build a scenario that fits.
Typically not. To accurately simulate real-world threats, red team engagements are covert, with only a small control group aware. This helps reveal your organisation’s true detection and response capabilities
