Data Retention What To Keep And Why
The 60-second version
Data retention involves determining how long to keep different types of data based on legal, regulatory, and business needs. Proper data retention policies help ensure compliance with laws like GDPR and CCPA, reduce storage costs, and minimize risks associated with data breaches. It also ensures that critical business information is available when needed.
What this solves (in real business terms)
Implementing a data retention policy helps your business comply with legal and regulatory requirements, avoiding fines and legal penalties. It reduces storage costs by eliminating unnecessary data and minimizes the risk of data breaches by limiting the amount of sensitive information stored. Additionally, it ensures that important business records are retained for operational and historical purposes.
What it costs (honest ranges)
The cost of implementing a data retention policy varies depending on the complexity of your data and the tools used:
- Data Retention Software: $1,000 - $10,000 per year
- Consulting Services: $2,000 - $15,000 (one-time or ongoing)
- Training and Awareness Programs: $500 - $5,000 per year
- Ongoing Maintenance: $500 - $3,000 per year
What can go wrong
Failing to implement a proper data retention policy can lead to legal penalties, increased storage costs, and higher risks of data breaches. Retaining data longer than necessary can result in compliance violations and unnecessary exposure to cyber threats. Conversely, deleting data too soon can lead to loss of critical business information and legal complications.
