5 Best Practices for Securing Data in Transit
Data in transit is vulnerable to interception and attacks, making security measures essential. In Canada, regulations like PIPEDA enforce strict safeguards to protect sensitive information. Here are five practical ways to secure data during transmission:
- Use Strong Encryption Protocols: Encrypt data with AES-256 and secure communication with TLS 1.2 or higher. Proper key management is key.
- Implement Strict Access Controls: Use multi-factor authentication (MFA) and role-based access control (RBAC) to limit access.
- Monitor and Audit Transfers: Track data movement with logging tools like SIEM and DLP to detect and respond to threats.
- Choose Secure File Transfer Solutions: Opt for systems with end-to-end encryption, compliance features, and integration capabilities.
- Keep Encryption Standards Current: Regularly update protocols (e.g., TLS 1.3) and rotate encryption keys to stay ahead of threats.
Canadian businesses must meet compliance requirements while reducing risks like breaches and financial loss. These strategies not only protect data but also build trust and ensure legal adherence.
How To Secure Data In Transit? – CountyOffice.org
1. Use Strong Encryption Protocols
Encryption acts as the first line of defence against data breaches during transmission. As information moves across networks, it becomes a target for eavesdropping and unauthorized access. Strong encryption protocols transform readable data into an unreadable format, ensuring that even if intercepted, it remains useless to attackers.
To secure communications, rely on trusted protocols like TLS (preferably TLS 1.2 or higher) for web interactions, HTTPS for safe browsing, and SFTP for encrypted file transfers. These standards have consistently demonstrated their reliability in protecting web traffic and API calls.
For sensitive data, implement AES-256 encryption, which offers robust protection and is considered virtually unbreakable with today’s computing capabilities. It’s also critical to use TLS 1.2 or newer versions, as older protocols have known vulnerabilities that can be exploited.
A stark reminder of the risks associated with outdated encryption is the 2017 WannaCry ransomware attack. This global cyberattack exploited weaknesses in the outdated SMBv1 protocol, causing major disruptions to hospitals, government agencies, and businesses worldwide. The fallout highlighted the financial and operational dangers of relying on obsolete security measures.
However, even the strongest encryption is ineffective without proper key management. Encryption keys should be unique to each user or session, rotated regularly, and stored securely to prevent misuse.
For Canadian organizations, robust encryption isn’t just a best practice – it’s a legal requirement under PIPEDA. These regulations mandate that personal and sensitive data be adequately protected during transmission, making encryption a key part of compliance.
Digital Fractal Technologies Inc integrates these encryption standards into their custom solutions, ensuring that Canadian businesses meet security and compliance needs. Their expertise guarantees that web and mobile applications are designed with secure encryption protocols right from the start, offering peace of mind for data in transit.

2. Implement Strict Access Controls
After encryption, the next layer of defence is strict access controls, which limit who can access sensitive data. This approach ensures that only authorized individuals, with proper identification, can interact with specific information.
One of the strongest tools against unauthorized access is multi-factor authentication (MFA). Instead of relying solely on passwords, MFA requires users to verify their identity through two or more factors, such as a password and a one-time code sent to their phone. For instance, in January 2023, a Canadian healthcare provider adopted role-based access control (RBAC) alongside two-factor authentication (2FA) for their electronic health record system. This change significantly reduced unauthorized access incidents and improved their audit scores.
Role-based access control is another essential tool. It ensures employees only have access to the data necessary for their job. For example, a marketing coordinator doesn’t need the same access privileges as a financial controller. This principle of least privilege minimizes the risk of data breaches and reduces the potential damage from compromised accounts.
Why is this so critical? According to Thales Group, 45% of companies have experienced a cloud-based data breach. These breaches are often linked to weak authentication methods or overly permissive access policies, making strong access controls non-negotiable.
To maintain security, permission management needs regular updates. Access policies should reflect organizational changes, and permissions must be revoked promptly when employees change roles or leave the company. Managed file transfer (MFT) solutions can help by offering features like robust authentication, audit trails, and precise permission settings. Tools such as Identity and Access Management (IAM) systems and Intrusion Detection Systems (IDS) further strengthen these defences by flagging suspicious activity and potential breaches.
For Canadian organizations, strict access controls are also critical for meeting regulatory requirements. The Personal Information Protection and Electronic Documents Act (PIPEDA) mandates these measures, and industries like healthcare and finance must adhere to even stricter standards under regulations like HIPAA or PCI DSS. Combined with encryption, access controls create a comprehensive security framework.
Companies like Digital Fractal Technologies Inc offer tailored solutions, integrating advanced access control features such as MFA, RBAC, and detailed audit logging. These tools help Canadian organizations align their security practices with both their operational needs and regulatory obligations.
Next, we’ll explore how continuous monitoring can take threat detection to the next level.
3. Monitor and Audit Data Transfers
Strong encryption and access controls are vital, but they aren’t enough on their own. Continuous monitoring and regular audits add an extra layer of oversight, enabling real-time threat detection and helping organisations meet Canadian regulations like PIPEDA.
Machine learning-based monitoring tools are particularly effective. They can analyse network traffic to detect unusual patterns and respond instantly – an essential feature since data in transit is often more vulnerable than data at rest. Every data transfer should be logged, including user identities, timestamps (e.g., 2025-11-19 13:22), file names, and destinations. These logs not only ensure accountability but also aid in investigating incidents.
Take a Canadian example: an energy company transferring sensitive files between offices in Toronto and Calgary through a managed file transfer solution. The system logs each transfer, capturing user information and file details. If files containing personal or financial data are sent to unauthorised recipients, automated alerts are triggered. Regular audits of these logs help the company stay aligned with PIPEDA and its internal security protocols.
Data Loss Prevention (DLP) tools add another layer of security by inspecting network traffic and blocking sensitive data headed for untrusted destinations. These tools can flag suspicious activity, such as large volumes of sensitive files being sent outside of business hours, and notify the security team immediately.
A detailed audit trail is invaluable for forensic investigations. Tools like Security Information and Event Management (SIEM) systems and managed file transfer platforms with built-in logging features can generate reports that meet Canadian regulatory standards. These reports assist in incident reconstruction, identifying breach sources, and implementing corrective actions.
For Canadian organisations, monitoring and auditing are not just good practices – they are mandatory. PIPEDA requires robust safeguards for protecting personal data during transmission. Additionally, industries handling payment data must adhere to PCI DSS standards.
Digital Fractal Technologies Inc offers tailored solutions to help Canadian businesses integrate monitoring and auditing systems into their existing infrastructure. Their customised software provides real-time visibility into data transfers across sectors like public services, energy, and construction, ensuring both security and compliance with PIPEDA.
Emerging technologies, such as blockchain, are also beginning to play a role. Blockchain can create immutable records of data transfers, ensuring both the integrity and authenticity of transactions. By combining these innovative tools with established monitoring solutions, organisations can build a comprehensive framework. The next step is selecting file transfer solutions that seamlessly integrate with these monitoring systems.

4. Select Secure File Transfer Solutions
Choosing the right file transfer solution is critical to safeguarding your business. When evaluating options, focus on security features, compliance requirements, and how well the solution integrates with your existing systems.
Encryption is key. Look for solutions with end-to-end encryption, specifically AES-256 or higher. This ensures your data remains protected during transmission. Additionally, secure key management is essential – your organisation should maintain control over encryption keys rather than relying entirely on third-party providers.
Strong access controls are another must-have. Solutions that include multi-factor authentication (MFA) and role-based access control (RBAC) add extra layers of security, ensuring only authorised personnel can access or transfer files.
The protocols a solution supports also matter. For example, SFTP (Secure File Transfer Protocol) uses SSH for both encryption and authentication, making it a strong choice for organisations with stringent security needs. TLS/SSL protocols secure web-based transfers, while HTTPS protects data exchanged online. A solution that supports multiple secure protocols can address varied use cases and align with compliance standards, strengthening your overall security framework.
For Canadian businesses, compliance with PIPEDA is essential. Your file transfer solution should offer encryption both in transit and at rest, detailed audit trails, and data residency options to keep personal information within Canada when required. Industry-specific regulations, like PCI DSS for payment data, should also be supported.
Integration capabilities are equally important. Check if the solution offers APIs, native connectors, or direct integrations with your existing systems, such as CRM platforms, ERP systems, cloud storage, or authentication directories like Active Directory. Seamless compatibility with your current workflows reduces deployment challenges and keeps operations running smoothly.
If your organisation handles high volumes or complex transfers, consider Managed File Transfer (MFT) solutions. These provide centralised control, automation, detailed monitoring, and advanced audit trails to meet both security and compliance needs.
Emerging technologies are also enhancing file transfer security. Machine learning, for instance, can monitor network traffic in real time to detect unusual activity, while blockchain technology creates immutable records of file transfers, improving auditability.
One example of a company addressing these needs is Digital Fractal Technologies Inc. They develop custom software with secure file transfer features tailored to Canadian businesses.

5. Maintain Current Encryption Standards and Key Management
Encryption standards are constantly changing to address new security threats and advancements in technology. What was secure just a few years ago might now leave your organisation exposed. To ensure safe data transmission, it’s crucial to stay updated on encryption protocols and manage cryptographic keys effectively.
Failing to keep up can have devastating consequences. Take the Equifax breach in 2017, for example – sensitive data from over 140 million individuals was compromised. A major factor? Outdated encryption practices and unpatched vulnerabilities in their web application framework. This case is a stark reminder of how quickly security lapses can spiral into massive data breaches.
Keeping Protocols Up to Date
Regular updates to encryption protocols are essential. Older standards like SSL and early versions of TLS have well-documented vulnerabilities that attackers can exploit. Canadian organisations should adopt modern protocols like TLS 1.3, which offers better security and performance, to stay ahead of emerging threats.
Best Practices for Key Management
Key management is just as important as protocol updates. Cryptographic keys must be securely generated, stored, rotated, and eventually destroyed. Tools like hardware security modules (HSMs) and key management services (KMS) provided by cloud platforms can streamline these processes and enforce consistent security policies.
- Rotate keys regularly: Aim for every 6–12 months or immediately after a suspected compromise. Automated key rotation can reduce IT workload while maintaining security.
- Secure access controls: Never hard-code keys into applications or transmit them in plain text. Instead, implement strict access controls, limiting key access to authorised personnel. Regularly audit key usage and access logs to detect any unauthorised activity.
Compliance and Legal Considerations
For Canadian businesses, adhering to PIPEDA (Personal Information Protection and Electronic Documents Act) means implementing safeguards like up-to-date encryption and secure key management. Regularly reviewing and updating encryption protocols demonstrates due diligence under Canadian law, helping to avoid fines, investigations, and reputational harm.
Staying Informed and Prepared
Keeping up with encryption standards requires continuous effort. Monitor updates from organisations like NIST and ISO, follow security advisories, and participate in industry forums. Regular training for IT teams ensures they’re aware of emerging threats and best practices, further strengthening your defences.

FAQs
How does multi-factor authentication improve the security of data during transmission compared to using just passwords?
Multi-factor authentication (MFA) adds an extra layer of security to data being transmitted by requiring users to confirm their identity through multiple methods. For example, it might involve entering a password and then using a one-time code sent to your phone. This combination makes it much more difficult for attackers to break in, even if they somehow get hold of your password.
MFA works by combining different elements: something you know (like your password), something you have (like your smartphone), or something you are (like your fingerprint). By using these together, the chances of unauthorized access are drastically reduced, helping to keep sensitive information safe while it’s being shared.
What risks could a business face if it doesn’t regularly update its encryption protocols and key management practices?
Failing to keep encryption protocols and key management practices up to date can leave your business exposed to serious risks. Using outdated encryption methods makes your systems more susceptible to cyberattacks, as hackers continuously develop sophisticated tools to exploit known vulnerabilities. The consequences? Data breaches, financial losses, and significant damage to your reputation.
On top of that, neglecting proper key management – like relying on weak or expired keys – can undermine the security of sensitive data during transmission. Regularly updating your encryption and key management systems ensures they meet the latest security standards, helping to prevent unauthorized access and maintain compliance with data protection regulations in Canada and worldwide.
Why should Canadian businesses comply with PIPEDA when securing data in transit, and what risks do they face if they don’t?
Canadian businesses must adhere to the Personal Information Protection and Electronic Documents Act (PIPEDA) to safeguard the privacy and security of personal data, especially when it’s being transmitted. Following these regulations not only strengthens customer trust but also shields businesses from potential legal troubles and financial penalties.
Failing to comply with PIPEDA can result in severe repercussions, including fines reaching up to $100,000 per violation, harm to a company’s reputation, and even loss of clientele. To meet PIPEDA requirements and protect sensitive information, businesses should prioritize secure data transmission. This includes using encryption, implementing secure protocols, and ensuring systems are regularly updated.
