What is a phishing exercise and how does it work?
A phishing exercise is a controlled simulation that tests how your employees respond to realistic social engineering attacks. Theos designs targeted campaigns that replicate adversary techniques, launches them against your agreed target population, and measures response across click rates, credential submission, and reporting behaviour. The findings identify where human-layer risk sits and direct awareness programme investment to where it will reduce the most exposure.
Will employees know the exercise is happening?
The notification approach is agreed during scoping. Most organisations choose to inform a small group of senior stakeholders while keeping the broader employee population unaware, so response reflects genuine behaviour under realistic conditions. Theos works with your team to agree the right notification structure before the campaign launches.
What languages can campaigns be delivered in?
Theos delivers phishing campaigns in English, Mandarin, Tagalog, Bahasa Indonesia, Bahasa Malaysia, Cantonese, and other regional languages on request. Multi-language campaigns reveal susceptibility patterns across the full workforce, particularly in APAC organisations operating across multiple countries.
How are campaign results measured?
Theos measures click rates, credential submission rates, attachment open rates (where applicable), and reporting rates across the target population. Results are broken down by department, pretext, and language. Each metric is benchmarked against the campaign context and accompanied by prioritised recommendations for awareness programme improvement.
Does Theos provide awareness training as part of the exercise?
Yes. Employees who engage with the simulation receive immediate post-click education explaining what they encountered and what to do when they face a real phishing attempt. Theos also provides recommendations for ongoing awareness programme development based on the exercise findings.
How does a phishing exercise connect to other Theos services?
Phishing exercise findings feed directly into red team pretext design, social engineering scope, and security awareness programme development. Organisations that work with Theos across multiple service lines find that susceptibility gaps identified in a phishing exercise inform the social engineering vectors used in the next red team engagement.
How often should phishing exercises be run?
Most regulatory frameworks recommend or require periodic testing of human-layer controls. Theos recommends a cadence based on your workforce size, your industry, and the pace at which your threat landscape evolves. Annual exercises provide a baseline; more frequent testing tracks improvement over time and maintains awareness as your workforce changes.
