Need help with data classification for your financial institution, including SaaS apps like Google Drive? Metomic automates the process and ensures compliance with regulations such as GDPR and NYDFS Part 500.
Heavily regulated financial institutions require effective data classification to safeguard sensitive information and ensure compliance. This is increasingly complex due to reliance on SaaS applications like Google Drive for data storage and collaboration.
Navigating these regulations is crucial, as non-compliance can result in significant fines and reputational damage.
This guide will help IT and security teams tackle data classification, covering data types, regulatory compliance, and best practices for protecting sensitive financial information.
Data classification is all about sorting information based on how sensitive it is and what could happen if it falls into the wrong hands. For financial organisations, this means pinpointing and tagging sensitive data—like customer bank details or transaction histories—so they know exactly how to protect it. For example, a financial institution might classify customer bank details stored in Google Drive as 'Confidential'.
By using data classification software, financial institutions can effectively safeguard their sensitive financial information. High-risk data might need stricter access controls and encryption, while less sensitive info can be handled with a bit more flexibility. This structured approach not only boosts security but also helps maintain trust with clients, which is crucial in the finance sector.
Data classification also fits neatly into existing security policies and frameworks, such as ISO 27001 and COBIT. These frameworks provide a roadmap for managing and protecting data, which is vital for staying on the right side of regulations and enhancing overall security.
With the global average cost of a data breach hitting $4.88 million in 2024, it’s clear that improperly managed data is an expensive business. Having a solid classification strategy can help mitigate risks and protect organisations from potentially massive financial losses.
In the world of finance, a variety of data types need careful classification to ensure they’re adequately protected.
Let’s break down some of the key categories:
Each of these data types requires different levels of classification. For example, while customer financial details and authentication data are classified as confidential, information like market research without sensitive data can be labelled as public.
It’s worth noting that the financial sector was the most breached industry in 2023, accounting for a staggering 27% of all breaches. With such high stakes, understanding what types of data need classification is crucial for safeguarding against threats and maintaining compliance.
Data classification is necessary for financial institutions because it helps minimise the risk of data breaches, a major concern in an increasingly dangerous cyber landscape, especially as the financial sector is the most targeted and breached industry.
By sorting data into categories like confidential, internal, and public, organisations can apply the right level of protection to sensitive information—especially personal financial details and authentication data. This tailored approach makes it much harder for attackers to access high-value data. The risk is heightened when sensitive data resides in cloud-based SaaS applications like Google Drive, where access controls and visibility need careful management.
Data classification also supports cybersecurity frameworks like Zero Trust, which requires that every access request is verified and authenticated before data is shared. Categorising data allows organisations to control access more effectively, ensuring only authorised personnel handle sensitive information.
The stakes are high in the financial sector, with the average cost of a data breach reaching $6.08 million – over $1 million higher than the global average cost of a data breach.
Mishandling data not only leads to costly breaches but can also damage an organisation’s reputation. Legal repercussions can include hefty fines for non-compliance, alongside the loss of customer trust—a vital asset for any financial institution.
Financial institutions operate in one of the most heavily regulated sectors, where compliance is non-negotiable. A wide range of regulations govern how sensitive data is handled, and failure to comply can result in significant penalties.
Here’s a quick overview of some key regulations:
For financial institutions, the stakes are high. Beyond fines, non-compliance can severely damage a business' reputation, leading to a loss of customer trust. Regulatory breaches can also result in operational disruptions, which can be costly and time-consuming to recover from.
These regulations extend to data stored and processed in SaaS environments like Google Drive, requiring financial institutions to ensure their use of these platforms meets compliance standards.

Financial institutions are increasingly leveraging the collaboration and accessibility benefits of SaaS applications like Google Drive. However, storing sensitive financial data in these environments introduces unique security considerations. Data classification plays a vital role in mitigating these risks.
As our internal report highlights, Google Drive, can house various types of financial data, from customer account details to internal reports. By implementing a data classification strategy, organisations can label files in Google Drive according to their sensitivity (e.g., using custom metadata fields or naming conventions). This allows for granular control over who can access, share, and download information.
For instance, files classified as "Confidential" can be restricted to specific teams, while sharing of "Restricted" documents outside the organisation can be automatically blocked.
A key challenge is the distributed nature of data across multiple SaaS applications. Data classification provides a consistent framework for understanding and managing data security regardless of where it resides. Tools like Metomic can automate the classification process within Google Drive, ensuring that as new files are created or uploaded, they are appropriately tagged and protected according to the organisation's policies. This proactive approach is essential for maintaining compliance and preventing data leaks in the cloud.
To keep financial data safe and compliant in SaaS apps, financial organisations should follow these key best practices for effective data classification:
Start by identifying the types of information you're handling, from customer financial details to internal business records.
Label your data as confidential, internal, or public, depending on how sensitive it is and what could happen if it's exposed.
Regularly update your data classification policies to account for new data types and any changes in regulations.
Use automation to limit access to sensitive data, making sure only authorised people can see or edit it.
Regularly check your data classification and access controls to catch any outdated labels or potential security gaps.
Collaborate with different teams to ensure data is classified properly according to both business needs and security guidelines.
Metomic plays a crucial role in assisting financial organisations with their data classification challenges in SaaS applications.
