A SaaS company with customer data should implement a number of security solutions. Some of the most important solutions are listed below, along with their estimated costs and references:
Secure Software Development Lifecycle (S-SDLC) - A process for developing secure software that includes implementing security controls throughout the development lifecycle. Depending on the size of the development team and the complexity of the software, this can cost between $5,000 and $50,000 per year. Reference: NIST SP 800-64 Rev. 2
Identity and Access Management (IAM) is a framework for controlling how users access applications and data. Depending on the number of users and applications, this can cost between $10,000 and $50,000 per year. Reference: NIST SP 800-63B.
Data Encryption - Protecting customer data from unauthorised access by encrypting it at rest and in transit. Depending on the amount of data and the level of encryption, this can cost between $5,000 and $20,000 per year. Reference: NIST SP 800-111.
Network Security - A set of solutions designed to safeguard the SaaS company's network and systems against external and internal threats. Depending on the size of the network and the level of security required, this can cost between $20,000 and $100,000 per year. Reference: NIST SP 800-41 Rev. 1
Incident Response - A process for responding to and mitigating the effects of security incidents. Depending on the complexity of the SaaS company's systems and the number of incidents, this can cost between $10,000 and $50,000 per year. Reference: NIST SP 800-61 Rev. 2.
Cloud Security - Security solutions for SaaS companies' cloud data and applications. Depending on the size of the cloud infrastructure and the level of security required, this can cost between $20,000 and $100,000 per year. NIST SP 800-146 is a reference.
It is important to note that the actual costs of implementing these security solutions can vary greatly depending on each SaaS company's specific needs and circumstances. These estimated costs are intended to provide a broad picture of the potential costs involved. It is strongly advised that SaaS companies consult with a qualified security professional to assess their specific needs and develop a customised security plan.
