Data security in the cloud is a concern for any type of company, from small to large, since cyber attacks in the corporate world have been growing in recent years. 

To get an idea, according to The State of Cloud Security , 79% of Brazilian companies that operate in the cloud have recently been the target of a cyber attack. Of the recorded incidents, 50% are from ransomware attacks, 29% from exposed data and 17% from crypto jacking.

In this scenario, it is possible to see that the accelerated digital transformation – mainly due to the effects of the pandemic – has led many companies to migrate to the cloud carelessly, without paying attention to a consistent and efficient security policy. 

All these myths that question cloud security end up contributing to many managers and CIOs still being afraid to invest in a migration to the cloud, a trend that, as evidenced by the data, is increasingly consolidating itself in the market and is proving to be essential for business growth.  

According to data from Gartner's research with IDC , the expectation for 2022 is that investments in cloud environments will be the target of 90% of medium and large companies.

But then: how to merge security in the cloud with investments in this area? The answers can be found below!

Cloud Data Security: Is the Cloud Really Secure?

Yes, the cloud is secure! 

As Caetano Notari, product manager at Sky.One , explains in episode 5 of Sky.Cast, Sky.One 's podcast:

Nobody has bigger security teams than Microsoft, Amazon and Google. Therefore, no data center will have the same level of security, after all they have a team that works 24 hours a day, 7 days a week focused on maintaining the security of the hosted data “.

It is important to highlight that, even if a good provider takes all the necessary precautions to guarantee cloud security, it is not possible to say that problems cannot happen at some point.

This happens not only in relation to the cloud. We have already followed news that hackers coordinated a ransomware cyberattack that affected almost 100 countries and managed to hijack data from gigantic companies. So nothing is completely failsafe.

The fact is that you cannot prevent all threats, but you can monitor them. And the first step is to use automated control systems that quickly detect irregular data patterns and signal that an intrusion is taking place.

When this notification occurs simultaneously, the enterprise can quickly and efficiently respond to the incident to stop the attack and minimize damage.

Cloud systems also usually have environmental protection through Firewalls and Security Groups, strong password requirement mechanisms, constant application of security updates to the operating system and isolation of the ERP environment from the most common attack vectors, among others. . 

Historics, logs, anomaly alarms in data entry: these are some of the functionalities that make an intelligent system for protection. With well-defined action and reaction protocols for compromise, you can quickly identify a breach and have the ability to act before the damage is truly harmful to the company.

At Sky.One , we have developed Auto.Sky Defender, which is the solution for monitoring and mitigating brute-force attacks.

Developed by the R&D area, it performs real-time monitoring of all unapproved access attempts on Auto.Sky scaling instances. Based on this information, it blocks all IPs considered to be offending.

How to ensure data security in the cloud?

Faced with the threats that the availability of systems and applications in the cloud may suffer, check if the cloud service provider company offers some of the features below in favor of the company's security.

1- Advanced firewalls 

With the mission of monitoring network traffic, firewalls are essential resources in data and application security. However, usually the simplest ones are used, performing only the inspection of the source and destination data.  

Thus, opting for more advanced firewalls means having the guarantee that the integrity of the content and the possibility of security threats will also be checked, through a more thorough scan. 

2- Intrusion detection

As we have seen, due to its remote availability and on any machine, many users can access the cloud system. 

Thus, a robust and qualified security system will be able to establish several levels of access detection, identifying such users and preventing intruders from overcoming the initial defenses of the network.

3- Event records

This functionality is necessary for a predictive and preventive analysis of possible intrusions, since the records will help analysts to understand the flow of access to the system and understand how threats can occur and by which paths. 

Thus, the records create reports and history about all events on the network, which helps in the search for solutions that prevent and block cyber attacks.

4- Data encryption

Data encryption is a strict data security protocol in the cloud, as it ensures that access to certain information is limited to authorized persons.

Thus, if there is an invasion attempt, the hacker will be prevented from accessing the files due to lack of access to the key. The method will also protect irregular access by the cloud service provider itself, as well as environment administrators.

5- Physical security

Data security in the cloud is much more efficient than in more traditional data storage models, such as on-premises data centers. Thus, completely migrating your system and applications to the cloud means achieving 24-hour monitoring, with qualified professionals who will check your system security at all times.  

In addition, it is necessary to reinforce the internal, employee and IT team's commitment to the security policy. It is therefore up to them to train and update them on the most frequent threats and how they can be avoided.

6- EDR Solutions

Most cyberattacks start with an endpoint (which can be a computer, tablet or even a smartphone) and then spread throughout the entire network. Therefore, the EDR solution was created to identify and act quickly when an intrusion is detected in any endpoint of the company.

For 2026, a global investment of more than 17 billion dollars in endpoint security is expected, according to data from Valuate Reports.

Cloud data security and GDPR compliance

Investment in data security in the cloud also seeks to meet the guidelines of the General Data Protection Law, in force since 2021 and with its supervisory body, the ANPD , already in operation.

This is because data leakage can result in different punishments according to the severity of the leak, reinforcing the importance of looking for a cloud provider that can guarantee the security of your company in the cloud and that is attentive to LGPD devices.

Among the foreseen penalties are: warning, simple fine of up to 2%, fine of up to 50 million reais, daily fines, blocking of personal data, blocking access to data and even suspension of core activity related to the use of data.

That is, depending on the structure of the size and segment of the company, an LGPD penalty can mean the bankruptcy of the business.

How Sky.One help companies with cloud data security?

Structuring and implementing the best cloud security practices that exist in the market, at Sky.One we focus on ensuring that cloud environments are always safe, both for our customers, as well as for their partners and collaborators.

Auto.Sky , one of our solutions, for example, encrypts all data and incorporates an Authentication Layer that securely isolates the ERP, without the need for VPNs and similar solutions. 

Auto.Sky authentication contains audit logs. The record of each session made by a user and the stored data are useful for internal audits of companies regarding the use of ERP systems by their employees.

In this way, we create validation routines and vulnerability tests to identify weaknesses and the need for constant improvements, as hackers themselves also evolve their ways of acting.

In addition, we offer solutions that help companies to innovate and modernize their IT structures, with security and agility, providing sophisticated cloud migration platforms and services, as well as systems integration.

For this, we have a specialized team ready to help the entire ecosystem of partners and customers available 24×7 in three different languages.

And what's your next step to bring data security to the cloud?

One of the requirements that cannot be overlooked in the digital transformation and migration to the cloud is data security, since in addition to the company having its production stagnant, due to an invasion or failure in the system, it will have credibility and market performance placed at risk. check.

In addition, it may be penalized by the LGPD and suffer great financial and image damage. Therefore, investing in the cloud requires investing in a qualified provider with good experience that provides cybersecurity services compatible with the needs of the business. And, if cybersecurity is a subject that interests you, check out our material and discover the main answers to help you take more security to the cloud.
