  The rapid digitalisation of SMEs, further expedited as a business continuity
measure against Covid19 impact, has brought along major cybersecurity
challenges, as it creates a fertile landscape for malicious actors, that want
to capitalise on the insufficient cybersecurity planning and preparedness of
SMEs to conduct low-effort, lucrative attacks. This paper constitutes a case
study on the cybersecurity challenges, specificities and the safeguarding of
the ATracker, a real-life data collection and analytics engine developed by the
SME Suite5. The ATracker has been successfully protected against attacks in
conjunction with the PUZZLE Framework, a holistic policy-based cybersecurity
solution, addressing major cybersecurity pillars and leveraging on the latest
scientific advancements in cybersecurity research.
