Phishing Zero Measurement – Understanding Digital Resilience
How vulnerable are your employees really?
Digital attacks are increasing every year. Yet many Dutch organizations lack real insight into how resilient employees are against phishing. At ALTA-ICT we perform a full baseline measurement to measure exactly that – before we start training.
In this blog, we explain:
-
How such a baseline measurement works
-
What exactly we measure
-
How the results are monitored
-
What the real return is
And more importantly, when a score is risky.
What is a phishing baseline?
A phishing baseline measurement is a one-time, realistic test that measures how employees respond to phishing emails. Without notice. Without advance notice. Only the IT department and management are informed. This creates a clean picture of the situation.
Our approach:
-
Within 2 weeks, each employee receives 2 unique phishing emails
-
Mails are segmented by department (HR, IT, Sales, C-level)
-
Industry and organization type are included in the content
Result: high relevance, higher learning effect, and realistic behavior.
On average, the phishing rate among companies is between 15% and 35%.
What exactly are we measuring?
Our baseline measurement goes beyond just “open rates.” This is what we measure:
-
📬 Number of emails sent: 1,078
-
👀 Open rate: 30.4%
-
🔗 Clicking on link: 9,1%
-
🧾 Data entered on fake site: 4,6%
-
📎 Attachment opened: 3.6%
-
💬 Responded to mail: 0,2%
-
🚩 Phishing reported: 51,1%
-
👥 Number of active users in test: 58
So we provide not just numbers, but direct insight into risk behavior.
What happens after the test?
Upon completion, you will receive a concrete advisory report including:
-
Overview and analysis of all behaviors
-
Comparison with benchmarks
-
Clear risk indicators
-
Concrete recommendations by behavior type
We discuss the results together in a video call. Directly, openly and without vague report language. Optionally, this is followed by a customized security awareness training.
Privacy & technology: what about it?
-
📧 Whitelisting in advance – no disruptions from spam filters
-
🔐 All data is anonymous – employees are not “judged”
-
📊 Generalized insights – unless deliberately chosen for open follow-up
Our goal is awareness, not a blame game. That is why we work AVG-proof and with ISO27001 substantiation.
Why start with a baseline measurement?
Many companies start training right away, but forget to measure what the starting point is. As a result, the return remains unclear. A baseline measurement offers immediate insight:
-
What is the real situation in your organization?
-
Where are the biggest risks?
-
How well do employees recognize phishing?
-
Specifically, what do you need to improve?
>10% click rate? Then immediate action is required.
Our target after 12 months of training: a phishing rate between 1% and 4%.

✅ Personal advice + follow-up via video call
Frequently Asked Questions
Do employees need to know anything in advance?
No, only the IT department and management were informed in advance.

Conclusion: measuring is knowing
A phishing baseline measurement is the way to turn awareness into action. Not assumptions, but facts. And build true digital resilience from there.
