Enables us to prioritize and effectively address critical security issues

Evidence-based reporting helps us to prioritize and solve critical security issues. The new visualization feature demonstrates how an attacker can enter the system, highlighting the potential path that can be exploited and outlining all the steps the attacker could take. With that visibility, we can ensure the perimeter is strong and attackers cannot enter, thus reducing the risk. It has helped us prioritize issues. The visibility into how an attack could happen is valuable. For example, it highlights the system vulnerability and outlines where an attack could propagate. The visualization helps me to prioritize remediation, and if I don't know where to start, I can check to see the score that enables me to prioritize issues. I am using infrastructure-as-code scanning, and it's one of the useful features. In pre-production, it identifies embedded secrets and misconfigurations, including issues with Kubernetes or some privileged containers. This feature allows us to pass the audit and secure IaC code so that it isn't easily exploitable by attackers. We can more proactively work to identify and resolve vulnerabilities by using the dashboard and the alerting system that SentinelOne provides. It helps us with audits and compliance. We can show the compliance in percentage. We can confidently say that our company or infrastructure is very secure. It has improved our security posture by 30% to 35%. It has reduced our false positives by 30%. It has helped teams collaborate better. The security team manages SentinelOne Singularity Cloud Security, and when it flags vulnerabilities, they are forwarded to DevOps for remediation. Previously, we needed to identify and report the issues, but there would be lapses in communication. Now, there is a centralized dashboard that anyone can look at and see the open issues and work on them.

Has provided automated threat detection and daily malicious activity insights while supporting seamless orchestration with existing dashboards

I would assess the integration of AWS GuardDuty with Threat Intelligence as majorly positive; no threat intelligence is 100% accurate, and there are a few false positives, but as a security engineer, this must be accepted, and overall, the response and service is good for us. We do not directly use AWS GuardDuty dashboard by itself, as we have our own integrated security dashboard; AWS GuardDuty gives the feed to that dashboard, and it's giving us a satisfactory view of how the security landscape looks. We use metrics such as zero-day threats, any malicious traffic, and any traffic which originates from OFAC countries to measure its effectiveness, as we are majorly into a financial institution, as any traffic that is from a malicious IP or a rogue device. I don't see any significant negative points regarding AWS GuardDuty; it's a good product to have if you're a cloud consumer. I rate AWS GuardDuty nine out of ten overall.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The user interface is well-designed and easy to navigate."

"SentinelOne's behaviour analytics are valuable because they detect anomalies and malicious behaviour that signature-based solutions might miss."

"Singularity Cloud Security's most valuable features are its ease of scalability and comprehensive security measures."

"SentinelOne Singularity Cloud Security stands out for its user-friendly interface and intuitive software, making it easy to navigate and use."

"Atlas security graph is pretty cool. It maps out relationships between components on AWS, like load balancers and servers. This helps visualize potential attack paths and even suggests attack paths a malicious actor might take."

"The most valuable features of SentinelOne Singularity Cloud Security are cloud misconfiguration, Kubernetes, and IaC scanning."

"Overall, I would rate it a ten on ten for cloud security."

"SentinelOne Singularity Cloud Security has improved our security posture."

More SentinelOne Singularity Cloud Security pros

"It helps us detect brute-force attacks based on machine learning."

"It kinda just gives us another layer of security. So it does provide some sort of comfort that we do have something that is monitoring for abnormal behavior."

"What we found most valuable in Amazon GuardDuty is its threat detection feature, especially because we were monitoring a huge number of AWS accounts, so we needed a solution that would monitor for any kind of malicious activity. The monitoring aspect of the solution was great because it gave us timely notifications if and when anything happened, and Amazon GuardDuty helped keep us on our toes to make sure we took action right away."

"The solution will detect abnormalities in the AWS workload and alert us so that we can monitor and take action."

"One of the advantages of cloud services is the ability to use them on demand. There's minimal installation involved; you can check the latest offerings and make new deployments while dismantling the previous ones. This approach keeps you ahead of potential services, showcasing the agility of AWS."

"Deployment is great, and we didn't face any big challenges."

"The solution provides AWS GuardDuty S3 protection, EKS runtime protection, and malware protection."

"GuardDuty is extensive in terms of configuration and security compliance."

More AWS GuardDuty pros

"The discovery feature is the most valuable. After you integrate your cloud environment, maybe an Azure or AWS, or a private environment hosted on VMware, it automatically starts discovering the number of servers that are running on that cloud and the number of services that you have done. It is a beautiful feature because, from a security standpoint, it is difficult to identify which VM is compliant or not when you keep on provisioning a number of VMs in the cloud. It also checks for compliance. It checks whether a system is compliant and whether antivirus is installed on a VM. If an antivirus is installed, it checks whether the antivirus is updated to the latest signature package or not. All these things are beautifully done by McAfee Cloud Workload Security. For communicating with the McAfee server, you need to install an agent on the VM. McAfee Cloud Workload Security gives you a direct opportunity to install an agent on a Windows machine. If you have a Windows cloud, you can directly push that agent onto the VM through your McAfee portal. It provides you a single dashboard view of all servers present in the cloud. It shows the servers on which the antivirus is already installed as well as the servers for which the antivirus installation is still pending. This dashboard view is a much-needed thing. It also has a centralized management, which makes it easy to use."

"The most valuable feature is the application control."

Cons

"The resolution suggestions could be better, and the compliance features could be more customizable for Indian regulations. Overall, the compliance aspects are good. It gives us a comprehensive list, and its feedback is enough to bring us into compliance with regulations, but it doesn't give us the specific objects."

"When you find a vulnerability and resolve it, the same issue will not occur again. I want SentinelOne Singularity Cloud Security to block the same vulnerability from appearing again. I want something like a playbook where the steps that we take to resolve an issue are repeated when that issue happens again."

"One area for improvement could be the internal analysis process, specifically the guidance provided for remediation."

"Once all components, including the cloud piece and container runtime piece, integrate further and incorporate an AI layer for better comprehension, it will greatly enhance the utility of Singularity Cloud Security."

"The area of improvement is the cost, which is high compared to other traditional endpoint protections."

"The application module focuses on the different codes and libraries that can be run on the machines. It is very important for Singularity EDR to detect what type of codes and what type of libraries can run in the machine. If they can implement a white list or a black list of codes or libraries that can be used in the machine, it would be very helpful. They can focus more on the application module."

"They need more experienced support personnel."

"The areas with room for improvement include the cost, which is higher compared to other security platforms. The dashboard can also be laggy."

More SentinelOne Singularity Cloud Security cons

"Improvement-wise, Amazon GuardDuty should have an overall dashboard analytics function so we could see what's in the current environment, and then in addition to that, provide best practices and recommendations, particularly to provide some type of observability, and then figure out the login side of it, based on our current environment, in terms of what we're not monitoring and what we should monitor. The solution should also give us a sample code configuration to implement that added feature or feature request. What I'd like to see in the next release of Amazon GuardDuty are more security analytics, reporting, and monitoring. They should provide recommendations and additional options that answer questions such as "Hey, what can we see in our environment?", "What should we implement within the environment?", What's recommended?" We know that cost will always be associated with that, but Amazon GuardDuty should show us the increased costs or decreased costs if we implement it or don't implement it, and that would be a good feature request, particularly with all products within AWS, just for cloud products in general because there are times features are implemented, but once they're deployed, they don't tell you about costs that would be generated along with those features. After features are deployed, there should a summary of the costs that would be generated, and projected based on current usage, so they would give us the option to figure out how long we're going to use those features and the option to keep those on or turn those off. If more services were like that, a lot more people would use those on the cloud."

"Cost changes. It's very expensive. If you turn on every feature, it's more than most commercial vendors. For smaller orgs, that doesn't make sense."

"It is evolving, and at the moment, I will just need it on a larger scale. Then, it will satisfy my demand, initially."

"The solution's user interface could be improved because it will help users to understand multiple options."

"Comparing AWS GuardDuty to similar products from Microsoft, Microsoft has a product called Sentinel, which is a completely integrated solution that basically does everything from vulnerability management to managing log analytics. This is something which AWS GuardDuty doesn't have since it's a separate service."

"Because it's a threat detection service, they need to keep up with the various threat factors because new threat factors and attack factors come up all the time."

"I work in a bank, and it would be good if AWS GuardDuty could be integrated with other monitoring and detection tools we use."

"The solution has to be integrated with new services that AWS adds like QuickSight, Managed Airflow, AppFlow and MWAA."

More AWS GuardDuty cons

"There is room for improvement in the pricing model."

"Its vulnerability assessment is not the best. We cannot identify the vulnerabilities that are related to the operating system by using McAfee Cloud Workload Security. I wish McAfee would add a vulnerability assessment tool that will not only identify the vulnerability but will also be able to generate a report so that the required patching can be done for the servers. Currently, McAfee Cloud Workload Security only integrates with AWS and Azure. If it can also integrate with GCP, Alibaba, and other cloud services available in the market, it would be good because not all people are using Azure and AWS."

Pricing and Cost Advice

"For pricing, it currently seems to be in line with market rates."

"The pricing is somewhat high compared to other market tools."

"Singularity Cloud Workload Security's licensing and price were cheaper than the other solutions we looked at."

"The pricing for PingSafe in India was more reasonable than other competitors."

"Its pricing was a little less than other providers."

"Their pricing appears to be based simply on the number of accounts we have, which is common for cloud-based products."

"Singularity Cloud Workload Security's pricing is good."

"PingSafe's pricing is good because it provides us with a solution."

More SentinelOne Singularity Cloud Security pricing and cost advice

"I don't have all the details in terms of licensing for Amazon GuardDuty, but my organization does have a license set up for it."

"The price of the solution is exactly right."

"In terms of the costs associated with Amazon GuardDuty, it was $1 per GB from what I recall. Pricing was based on per gigabyte. For example, for the first five hundred gigabytes per month, it'll be $1 per GB, so it'll be $500. If your usage was greater, there's another bracket, for example, the next two thousand GB, then there's an add-on cost of 50 cents per GB. That's how Amazon GuardDuty pricing slowly goes up. I can't remember if there was any kind of additional cost apart from standard licensing for the solution. Nothing else that at least comes to mind. What the service was charging was worth it. That was one good thing when using Amazon GuardDuty because my company could be in a certain tier for a certain period. My company wasn't under a licensing model where it could overestimate its usage and under-utilize its usage and pay much more. This was what made the pricing model for Amazon GuardDuty better."

"80 percent of the customers are using AWS GuardDuty, and we recommend it due to its low cost, especially for small customers, ranging from five to ten dollars a month. In our policies, we enforce the usage of this service, making it a recommended practice for security."

"Pricing is determined by the number of events sent."

"GuardDuty only enables accounts in regions where you have an active workload. If there are places where you don't have an active workload, you wouldn't even enable them. That's one area where they could allow you to cut down your cost."

"The platform is inexpensive."

"We use a pay-as-you-use license, which is competitively priced in the market."

"It is not an expensive product. I am in the Indian market, and it is one of the most reliable and cost-effective solutions."

SentinelOne

Amazon Guard Duty is a continuous cloud security monitoring service that consistently monitors and administers several data sources. These include AWS CloudTrail data events for EKS (Elastic Kubernetes Service) audit logs, VPC (Virtual Private Cloud) flow logs, DNS (Domain Name System) logs, S3 (Simple Cloud Storage), and AWS CloudTrail event logs.

Amazon GuardDuty intuitively uses threat intelligence data - such as lists of malicious domains and IP addresses - and ML (machine learning) to quickly discover suspicious and problematic activity in a user's AWS ecosystem. Activities may include concerns such as interactions with malicious IP addresses or domains, exposed credentials usage, or changes and/or escalation of privileges.

GuardDuty is able to easily determine problematic AWS EC2 (Elastic Compute Cloud) instances delivering malware or mining bitcoin. It is also able to trace AWS account access history for evidence of destabilization. such as suspicious API calls resulting in changing password policies to minimize password strength or anomalous infrastructure deployments in new or different never-used regions.

GuardDuty will continually alert users regarding their AWS environment status and will send the security discoveries to the GuardDuty dashboard or Amazon CloudWatch events for users to view.

Users can access GuardDuty via:

AWS SDKs: Amazon provides users with several software development kits (SDKs) that are made up of libraries and sample code of numerous popular programming languages and platforms, such as Android, iOS, Java, .Net, Python, and Ruby. The SDKs make it easier to develop programmatic access to GuardDuty.
GuardDuty HTTPS API: This allows users to issue HTTPS requests directly to the service.
GuardDuty Console: This is a browser-based intuitive dashboard interface where users can access and use GuardDuty.

Amazon Elastic Kubernetes Service (Amazon EKS)

Kubernetes protection is an optional add-on in Amazon GuardDuty. This tool is able to discover malicious behavior and possible destabilization of an organization's Kubernetes clusters inside of Amazon Elastic Kubernetes Service (Amazon EKS).

When Amazon EKS is activated, GuardDuty will actively use various data sources to discover potential risks against Kubernetes API. When Kubernetes protection is enabled, GuardDuty uses optional data sources to detect threats against Kubernetes API.

Kubernetes audit logs are a Kubernetes feature that captures historical API activity from applications, the control plane, users, and endpoints. GuardDuty collates these logs from Amazon EKS to create Kubernetes discoveries for the organization's Amazon EKS assets; there is no need to store or turn on the logs.

As long as Kubernetes protection remains activated, GuardDuty will continuously dissect Kubernetes data sources from the Amazon EKS clusters to ensure no suspicious or anomalous behavior is taking place.

Amazon Simple Cloud Storage (S3) Protection

Amazon S3 allows Amazon GuardDuty to actively audit object-level API processes to discover possible security threats to data inside an organization's S3 buckets. GuardDuty continually audits risk to the organization’s S3 assets by carefully dissecting AWS CloudTrail management events and AWS CloudTrail S3 data events. These tools are continually auditing various CloudTrail management events for potential suspicious activities that affect S3 buckets, such as PutBucketReplication, DeleteBucket, ListBucket, and data events for S3 object-level API processes, such as PutObject, GetObject, ListObject, and DeleteObject.

Reviews from Real Users

“The most valuable features are the single system for data collection and the alert mechanisms. Prior to using GuardDuty, we had multiple systems to collect data and put it in a centralized location so we could look into it. Now we don't need to do that anymore as GuardDuty does it for us.” - Arunkumar A., Information Security Manager at Tata Consultancy Services
