With the advancement of hybrid and remote work models, concern for information security has gained even more relevance for CEOs, directors, and IT managers. After all, in the home office, company information no longer circulates solely within protected corporate networks and starts transit through personal devices, home Wi-Fi networks, and external services. This expands vulnerable points and can jeopardize sensitive data of both the company and clients and consumers. 

According to IBM Security (2024), the average cost of a data breach in companies with remote teams is up to 20% more expensive than in organizations operating exclusively in the in-person model. And this impact goes beyond the financial, directly affecting brand reputation, the trust of clients and partners, and, in more critical cases, business continuity.

In this package of concerns regarding data security in home offices, there is also compliance with the LGPD (General Data Protection Law), which requires the appropriate and secure processing of personal data, regardless of the workplace. So many points of attention make it clear that ensuring a secure ecosystem in flexible work is no longer an option, but a necessity for companies that wish to be part of the silent revolution of flexible work and maintain their role of trust in the market.

In this article, you will discover that investing in security in home offices is not just about acquiring technologies: it is about building an organizational culture capable of reducing human errors, one of the main causes of cyber incidents in remote environments. To find out if your company is on the right track, we have put together a practical checklist at the end of this article with the main points of attention involving this topic. But after all, where should you start?

Create clear security policies for remote work

If your company does not yet have a security policy for home offices, perhaps it is time to create one. It is essential to develop and communicate clear rules for flexible work, and this goes beyond an official document: we are talking about a practical and accessible guide for all employees. These policies must address in detail the use of personal devices (BYOD - Bring Your Own Device), establishing what can and cannot be accessed, and how this access must be protected.

This guide should also include clear guidelines on accessing public Wi-Fi networks, warning about the risks and best practices to avoid intrusion by third parties. The policy should also establish official channels for sharing documents, as well as dictate backup practices, ensuring that critical data is saved regularly and securely. 

Well-defined policies not only reduce vulnerabilities but also create a security culture where each employee becomes an active agent in protecting the company's data.

Invest in VPN and end-to-end encryption

Ensuring that all access to corporate systems is done through VPNs (Virtual Private Networks) is one of the most effective measures to establish a secure path between the employee's device and the company's network. The VPN encrypts data traffic, making it unreadable to anyone trying to intercept it. In addition, data encryption must be mandatory. This means that information must be encoded when sent (in transit) and when stored on servers or devices (at rest).

For companies dealing with confidential customer information, such as financial or health data, this is an essential and non-negotiable resource. Encryption drastically minimizes the risk of interception and misuse by malicious actors, even if they manage to get some form of access. It is the guarantee that even if the data is reached, it will be useless to the attacker.

Manage devices and establish multi-factor authentication 

In the remote model, the line between personal and corporate devices can become blurred, which increases the attack surface. Therefore, it is essential to implement mobile device management (MDM) solutions. MDM allows the IT team to remotely configure, monitor, and manage devices accessing company resources, ensuring indeed that they are updated, with security software installed, and in compliance with internal policies.

Another powerful digital security barrier to protect critical systems and applications is two-step verification, also known as two-factor authentication. This type of login usually combines passwords, tokens, mobile phones, and biometrics, making credential theft-based attacks difficult. Even if a criminal obtains an employee's password, they would still need the second factor of authentication to gain access, significantly reducing the impact of a compromised device or account.

Continuously train employees

Many cyberattacks exploit the weakest link in security: human behavior. Therefore, promoting periodic and dynamic training on cybersecurity best practices is indispensable. This training must go beyond theory, focusing on practical examples and simulations so that employees know how to identify and react to common threats.

Topics such as fake emails, manipulation strategies, and identifying suspicious links or malicious attachments must be constantly addressed. Companies that invest in training significantly reduce the number of incidents caused by human error, turning their employees into an active line of defense against cybercriminals. 

Invest in monitoring and response solutions 

Security incidents can happen. In view of this fact, investing in continuous monitoring solutions, such as threat detection and response systems (EDR - Endpoint Detection and Response and XDR - Extended Detection and Response), is crucial. These tools allow your company to quickly identify suspicious activities, from unusual device behaviors to unauthorized access attempts, and act before an attack consolidates or spreads.

Defining an incident response plan for remote environments must also be part of the strategy. This plan should detail the steps to be followed in the event of a breach, who is responsible, how internal and external communication will be managed, and what measures will be taken to contain or remediate the attack. Having a well-defined plan reduces downtime and the damage caused by an intrusion.

Strengthen cloud and service security

With the increasing use of SaaS (Software as a Service) applications, cloud storage, and collaborative tools, organizations must periodically review the security settings of these services. It is a common mistake to believe that cloud security is the exclusive responsibility of the provider. Cloud security is a shared responsibility.

This includes strict access controls, ensuring that only authorized users have the necessary permissions for each type of information. Permission reviews must be done regularly, especially when employees change roles or leave the company. Therefore, the audit logs of these services must be monitored to identify unusual activities. Finally, integration with existing corporate security tools (such as SIEM - Security Information and Event Management) strengthens visibility and control over cloud data, ensuring a unified security posture.

CodeBit offers several cloud infrastructure solutions. Among them is the CloudOps Review, which performs a complete scan of the cloud architecture, ensuring the protection of hosted data and systems. In addition to the diagnosis, the CloudOps Review includes vulnerability testing, LGPD adaptation strategies, and evaluations at various levels.
We have created a quick checklist for you to reflect on your company's data security during flexible working hours, meaning in remote or hybrid formats. Check it out below.
