Incorporating security into agency offerings is essential not only for increasing revenue but primarily for ensuring client satisfaction and loyalty. As security becomes a more critical element in client relationships, agencies that proactively integrate security measures can distinguish themselves from competitors and foster long-term partnerships. This shift is driven by new legal guidelines, such as the General Data Protection Regulation, which mandates businesses to focus on preventive measures, and by market leaders like Google, which prioritize security in their services. Agencies can leverage tools like Detectify to conduct security tests, monitor vulnerabilities, and provide detailed reports, converting one-off projects into retainers and enhancing their service portfolio. The increased focus on security not only helps protect brand reputation by preventing breaches but also aligns with evolving digital marketing standards, where security is becoming as crucial as site speed and design. By adopting a security-oriented approach, agencies can achieve higher-value contracts and maintain a competitive edge in the rapidly changing digital landscape.
