Features Offered By Top 10 Cloud Security Companies

1. Continuous Vulnerability Scans

Cloud security companies should offer continuous and comprehensive vulnerability scans to assess and find any vulnerabilities within the cloud system. It should beagle to find vulnerabilities based on known vulnerabilities from CVEs, intel, OWASP Top 10, and SANS 25. It should also be able to scan behind the logins and find any business logic errors. 

2. Regular Penetration Tests

Regular penetration tests are crucial for the security of a cloud environment by both the customers and the providers to analyze and exploit the vulnerabilities within the security system.

The results of such a pentest will detail the flaws found along with the measures that can be taken to fix them before any malicious attackers take advantage of them. 

3. Firewalls

A cloud-based firewall is a non-traditional solution to maintaining security for the data stored and transmitted with your cloud. These firewalls are hosted in the cloud itself. Cloud-based firewalls are easily scalable according to the needs of the cloud provider or the customer.  

4. Data Encryption

Securing the data that is being transmitted and stored by cloud customers is absolutely critical. This is where data encryption comes into play. Encrypting data that is at rest and in transit using Transport Layer Security. This makes sure that the data can not be decrypted by the wrong parties thus maintaining confidentiality. 

5. Intrusion Detection

Ensure that the company you choose for your cloud’s security has the right measures to detect any unauthorized activities and provide real-time alerts for the same. Machine learning can help cloud security measures recognize patterns and thereby detect activities that fall outside the established patterns in security. 

6. Compliance

Cloud security companies also ensure that as a cloud customer or a provider, the compliance you must maintain like HIPAA, PCI-DSS, GDPR, and other data protection laws are abided by.

Factors To Consider While Opting for A Cloud Security Company

1. Your Needs

Ensure that the needs of the company are prioritized and listed so that you can check the features offered by a potential cloud security provider against your cloud-based company’s needs and requirements. 

Does your company require a cloud security solution that can be integrated into the CI/CD pipeline, or is it to achieve and maintain certain regulatory requirements like that of HIPAA, PCI-DSS, SOC 2, ISO 27001, and others, or is it to maintain your side of the security according to the shared responsibility model. These are some of the common reasons why organizations and cloud providers opt for cloud security companies. 

2. Scalability

Ensure that the cloud security solution you choose provides a good scope for scalability if the need arises. This means that the solution must be capable of expanding or reducing its services in accordance with your company’s scaling. 

Larger companies often require scalable services that can be extended based on their growing needs and company size. 

3. Pricing

Ensure the pricing range offered by the cloud security companies you have narrowed down fits well within the budget set by your cloud-based company. The company you choose must also provide the necessary features for a seamless cloud security experience that protects your confidential information in a holistic manner.  

4. Reputation 

Yet another factor to consider when opting for a cloud security company is its reputation and experience in the field. Longer experience does not necessarily mean a better reputation all the time. Thus vet your choices thoroughly by going through reviews and recommendations by clients. 

5. Customer Support

Understand the extent of the customer support provided by the company. Check out reviews by current or previous customers to understand their customer service experience with the cloud security companies you are looking to hire. 

Make sure that customer service is available when you’re in need of it and that they are available through calls and e-mails for easier communication. 

6. Features

Compare the different specifications offered by cloud security companies. Features like business logic error and intrusion detection, scan-behind-logins, and holistic VAPT services are some important features that should be offered by a good cloud security company. 

3 Methodologies Opted By Cloud Security Companies For VAPT

Black Box

Black-box testing refers to the method of testing where the pentesting company is not aware of any details regarding the target. No information in the cloud environment is divulged making this the most realistic hacker-style testing. This type of testing is functional and focuses on the external features of the cloud. 

White Box

White box penetration testing or glass-box penetration testing is where the testing team is aware of all the internal cloud details of the server to be tested. This type of testing is more required while applications are in development as it offers the testing to find vulnerabilities within the known internal cloud server. 

Gray Box

Gray box testing or translucent testing is where the testing team is only partially aware of the relevant cloud information. It can be done by both end users and developers since it’s a midway ground between a black and white box.
