Email Security in Practice: The ams OSRAM Case Study

Implement email security successfully

Email remains the most important means of communication in day-to-day business, but it is also one of the most common gateways for cyberattacks.

Before a project begins, there is often no complete overview of all email sending sources, while individual domains may not be adequately protected by SPF, DKIM or DMARC, potentially enabling spoofing attempts. Fraudulent emails increase the workload for support teams and may adversely affect the deliverability of legitimate messages. At the same time, security and compliance requirements are increasing as a result of standards and regulatory provisions.

Objectives of the case study

The case study aimed to protect the company’s digital identity in the long term and make its email communications more secure.

The key objectives were:

  • Protecting the brand identity against phishing and spoofing
  • Improving email deliverability to customers and partners
  • Ensuring transparency regarding all legitimate and illegitimate email sending sources
  • Meeting current security and compliance requirements
Infographic titled “Email Security as a Critical Success Factor”. It states that over 90% of cyberattacks begin with a phishing email, 360 billion emails are sent worldwide every day, and cybercrime costs Germany over EUR 200 billion annually. Over 30% of organisations still have no DMARC record, leaving their domains vulnerable to identity theft and brand misuse. A comparison shows that implementing email security involves predictable, low costs, causes no disruption, builds trust and meets legal and compliance requirements. By contrast, a cyberattack results in very high, unpredictable costs, disruptions and outages, loss of trust, fines and liability risks. The graphic concludes that email security protects brand reputation, deliverability and business continuity.

“Email security is one of the fundamental protective measures. With just a few settings, we can all achieve a significant improvement for everyone by making email more traceable and thereby considerably reducing spam, fraud and phishing – without having to spend a single Euro on a tool! This case study describes the specific steps that every company can take.”

The three core technologies covered in the case study

  • SPF (Sender Policy Framework)
  • DKIM (DomainKeys Identified Mail)
  • DMARC (Domain-based Message Authentication, Reporting and Conformance)
