Data privacy regulations have shifted from a background concern to a boardroom priority. With the General Data Protection Regulation (GDPR) setting the global standard, and local laws like the CCPA in California following suit, organizations face a complex web of compliance requirements. At the center of this web sits the Data Protection Officer (DPO).
For many companies, hiring a full-time, in-house DPO is neither feasible nor financially prudent. The talent pool is shallow, salaries are high, and the workload for smaller organizations often doesn’t justify a 40-hour work week. This is where the concept of “retaining” a DPO as a Service (DPOaaS) comes into play.
Retaining a DPO as a Service involves contracting an external expert or agency to fulfill the mandatory or voluntary role of a Data Protection Officer. This guide explores how to effectively find, hire, and retain these services to ensure your organization remains compliant without breaking the bank.
What is DPO as a Service?
DPO as a Service (DPOaaS) is an outsourcing model where an organization hires an external privacy expert or a specialized firm to act as its designated Data Protection Officer.
Rather than adding a permanent employee to the payroll, the company signs a service agreement with a provider. This provider fulfills all the statutory tasks required by Article 39 of the GDPR (and similar laws), such as monitoring compliance, advising on Data Protection Impact Assessments (DPIAs), and acting as the contact point for supervisory authorities.
This model is particularly popular among small to medium-sized enterprises (SMEs) and organizations that process data but do not require a full-time presence. It offers flexibility, cost control, and access to a team of experts rather than a single individual.
Why do companies choose to outsource the DPO role?
Addressing the conflict of interest
One of the most challenging aspects of appointing an internal DPO is avoiding a conflict of interest. Under GDPR Article 38(6), a DPO cannot hold a position that leads them to determine the purposes and means of processing personal data. This rules out CEOs, COOs, Heads of Marketing, Heads of HR, and often IT Managers. Retaining an external service eliminates this conflict entirely, as the external DPO has no vested interest in the company’s commercial operations.
Cost efficiency and continuity
A senior DPO commands a significant salary. When you factor in benefits, recruitment costs, and ongoing training, the expense is substantial. DPOaaS operates on a retainer or subscription basis, which is typically a fraction of the cost of a full-time hire. Furthermore, retaining a service ensures continuity. If an in-house DPO calls in sick or resigns, the company is left vulnerable. A service provider, however, has backup consultants ready to step in.
Access to broader expertise
When you retain a DPO service, you aren’t just hiring one person; you are usually gaining access to a collective knowledge base. Privacy laws intersect with IT security, legal frameworks, and industry-specific regulations. An external firm often employs legal experts, IT security auditors, and compliance specialists who collaborate to solve complex client issues.
How to assess if you need to retain a DPO
Before you begin the search for a provider, you must determine if your organization is legally required to have one. Even if it is not mandatory, appointing one voluntarily is often considered a best practice that builds trust with customers.
According to the GDPR, you must designate a DPO if:
- You are a public authority: The processing is carried out by a public authority or body.
- You monitor people on a large scale: Your core activities require regular and systematic monitoring of data subjects on a large scale.
- You process sensitive data: Your core activities involve processing strictly sensitive data (like health records, biometric data, or criminal convictions) on a large scale.
If you fall into these categories, retaining a DPO is not optional—it is a legal necessity.
5 steps to retaining the right DPO service
Selecting the right partner is critical. The DPO is a protected role with significant independence. Once you appoint them, they are difficult to dismiss simply because you disagree with their compliance advice. Therefore, the vetting process must be thorough.
1. Define the scope of work
Before approaching vendors, clarify what you need. Are you looking for a “minimal viable compliance” approach where the DPO simply audits and reports? Or do you need a hands-on partner who will help draft policies, train staff, and manage data subject access requests (DSARs)? The scope will dictate the cost of the retainer.
2. Verify credentials and experience
Data privacy is not a field for generalists. Look for specific certifications such as CIPP/E (Certified Information Privacy Professional/Europe) or CIPM (Certified Information Privacy Manager). Beyond paper qualifications, ask for case studies. Has the provider worked with other companies in your specific sector? A DPO familiar with healthcare data faces different challenges than one working with e-commerce retail.
3. Check for insurance and liability
When you retain an external service, you need to understand where the liability sits. While the organization (the controller) remains ultimately responsible for compliance, the DPO service should carry professional indemnity insurance. This protects your business in the event that the DPO gives negligent advice that leads to a fine or data breach.
4. Evaluate communication protocols
A DPO must be accessible. GDPR Article 38 requires that the DPO be involved “properly and in a timely manner” in all issues relating to the protection of personal data. During the hiring process, ask:
- What is the response time guarantee (SLA)?
- Will we have a dedicated account manager, or will we speak to a different consultant every time?
- How do they handle emergency situations, such as a data breach on a weekend?
5. Review the service agreement carefully
The contract serves as the backbone of the relationship. Ensure the retainer agreement covers:
- Hours included: Is it a flat fee for unlimited advice, or is there a cap on hours per month?
- Exit strategy: How much notice is required to terminate the service?
- Conflict checks: How does the firm ensure they don’t represent a competitor in a way that creates a conflict?
Structuring the retainer: Fixed fee vs. Hourly
When retaining a DPO service, you will generally encounter two pricing models. Choosing the right one depends on your organization’s maturity regarding data privacy.
The Fixed-Fee Retainer
This is the most common model for DPOaaS. The client pays a monthly or annual fee. In exchange, the provider acts as the named DPO with the supervisory authority. This fee usually covers:
- Annual compliance audits.
- A set number of hours for ad-hoc advice.
- Reviewing a specific number of contracts or DPIAs.
Best for: Organizations with stable data processing activities who need a safety net and statutory compliance.
The Hourly or “Bank of Hours” Model
Some providers charge a lower base retainer for the “named DPO” status and then bill hourly for any actual work performed. Alternatively, you might buy a “bank” of 50 hours to be used over the year.
Best for: Companies undergoing significant changes, such as a software migration or a merger, where the workload is unpredictable and likely to spike.
How to manage the relationship after hiring
Retaining the DPO is just the start. To get value from the service (and avoid fines), the relationship requires management.
Integrate them into project management workflows
A common mistake companies make is treating the external DPO as an outsider who only hears about projects after they launch. This is “privacy by disaster.” Instead, integrate your DPO into the early stages of project management. If you are launching a new app feature or switching CRM providers, the DPO should be consulted during the design phase (Privacy by Design).
Establish regular reporting cycles
Don’t wait for a breach to talk to your DPO. Schedule quarterly compliance reviews. The DPO should provide a report detailing the organization’s current compliance status, upcoming regulatory changes, and risks identified. This report should be presented to the board or highest management level, ensuring that privacy remains a strategic priority.
Grant necessary access and resources
For a retained DPO to be effective, they need access to your internal systems, data processing records, and key staff. If you wall off your external DPO from the IT department, they cannot effectively monitor security measures. Ensure your internal teams understand that the external DPO operates with the authority of senior management.
Common challenges with DPO as a Service
While outsourcing offers many benefits, there are pitfalls to avoid.
The “Rubber Stamp” DPO
Some low-cost providers operate as “sign-off factories,” effectively rubber-stamping risky processing activities without genuine scrutiny. This provides a false sense of security. If a regulator investigates, they will quickly identify that the DPO was not performing their duties, which can lead to higher fines for negligence.
Lack of Cultural Fit
An external consultant may struggle to understand the company culture. If the DPO is seen as the “police” who always says no, employees will find workarounds (shadow IT). It is vital to retain a provider who understands how to enable business goals while maintaining compliance, rather than blocking innovation entirely.
What happens if you don’t retain a DPO?
If your organization is legally required to have a DPO and fails to appoint one, you are in direct violation of the GDPR. This can attract administrative fines of up to €10 million or 2% of the company’s total worldwide annual turnover, whichever is higher.
Beyond the fines, the lack of a DPO often leads to poor data handling practices. Without an expert overseeing data retention policies, security measures, and breach protocols, the risk of a cyber incident increases. When a breach occurs, the absence of a DPO is viewed as an aggravating factor by regulators, leading to stricter penalties.
Frequently Asked Questions (FAQ)
Can a single DPO represent multiple companies?
Yes. The GDPR explicitly allows a single DPO to act for a group of undertakings, provided the DPO is easily accessible from each establishment. This legal provision is the foundation of the DPO as a Service model.
Who is liable if there is a data breach: the company or the external DPO?
The company (the Data Controller or Processor) is always liable for compliance with data protection laws. The external DPO is generally not personally liable for the company’s non-compliance. However, the DPO service provider could be liable to the company for breach of contract or negligence if they failed to provide accurate advice.
How much does DPO as a Service cost?
Costs vary widely based on the size of the company and the complexity of data processing. For a small business, retainers can start from as low as $500 to $1,000 per month. For larger enterprises requiring significant hands-on involvement, monthly fees can range from $3,000 to $10,000+.
Can we switch from an external DPO to an internal one later?
Absolutely. Many startups retain a DPO as a Service during their growth phase. Once the company reaches a certain size where the privacy workload justifies a full-time role, they often transition to hiring an in-house expert. A good service provider will even assist in the handover process.
Securing your organization’s future
Retaining a DPO as a Service is a strategic move that balances compliance, cost, and expertise. It allows organizations to focus on their core business activities while ensuring that personal data is handled legally and ethically.
However, the “retainer” is not a product you buy and put on a shelf. It is an active professional relationship. Success comes from selecting a provider with the right industry experience, integrating them into your operational workflows, and viewing them as a partner in your business growth rather than just a regulatory checkbox.
By following the vetting steps and management strategies outlined above, you can turn data privacy from a risk factor into a competitive advantage.
