Compliance with these frameworks is essential to avoid fines, legal action, and reputational damage.

How much should E-commerce companies spend on cybersecurity?

Industry benchmarks suggest that E-commerce companies should spend between 5% and 10% of their IT budget on cybersecurity. However, the actual amount will depend on the size and complexity of the business, the sensitivity of the data being processed, and the regulatory requirements that apply. A risk assessment can help determine the appropriate level of investment in cybersecurity.

What is the first step to improve E-commerce security?

The first step to improve E-commerce security is to conduct a security risk assessment. This will help you identify your key assets, vulnerabilities, and security risks. Once you have a clear understanding of your security posture, you can prioritize and implement appropriate security measures.

How can small E-commerce companies afford enterprise security?

Small E-commerce companies can afford enterprise security by leveraging cloud-based security solutions, focusing on essential security controls, and implementing a risk-based approach to security. Cloud-based solutions are often more cost-effective than on-premise solutions, and a risk-based approach allows you to prioritize the most critical security risks.

What security certifications are important for E-commerce?

Relevant security certifications for E-commerce include CISSP, CISM, CISA, and PCI QSA. These certifications demonstrate that an individual has the knowledge and skills to implement and manage a comprehensive security program. For the company itself, SOC 2 certification can be valuable for demonstrating security posture to customers and partners.

How often should I perform vulnerability scans on my E-commerce website?

Vulnerability scans should be performed regularly, ideally on a weekly or monthly basis. More frequent scans may be necessary if you are making frequent changes to your website or applications. Continuous monitoring solutions, like Secably AI Scanner, can provide real-time vulnerability detection.

What is the best way to protect my E-commerce website from DDoS attacks?

The best way to protect your E-commerce website from DDoS attacks is to use a Content Delivery Network (CDN) or a dedicated DDoS mitigation service. These services distribute traffic across multiple servers, making it harder to overwhelm your website. They also use various techniques to identify and block malicious traffic.
