About Tigera

Tigera Calico Enterprise software from Tigera is an enterprise software company providing security and compliance solutions for Kubernetes platforms. Kubernetes or K8 is an open-source container management and orchestration platform that provides the tools to automate, deploy, and scale applications and services. K8 works by clustering groups of hosts on different operating systems to manage containerized workloads for the smooth functioning of applications. As the platform is open source, it can be subjected to a number of security risks and threats, and that’s where Tigera comes in.

Tigera is built on the foundation of three principles that focus on security, including:
  1. Providing security controls
  2. Implementing access controls
  3. Providing a platform for visibility and troubleshooting
Providing security controls
Implementing access controls

Tigera works to give Kubernetes platforms Zero Trust security and continuous compliance and security and compliance solutions to tackle Kubernetes security challenges, with support for on-premises, multi-cloud, and legacy settings. Tigera powers the bulk of Kubernetes distributions and is integrated with a wide array of Kubernetes providers.

Tigera is the industry leader in Kubernetes in terms of security and observability, and it has diversified its product offering as they currently provide product editions to support different functionalities, including:
  • Calico Open Source, which is specifically designed to manage open-source networking and provide security for Kubernetes, Docker EE, OpenStack, and other application platforms for superior scalability functionality, seamless communication, and performance
  • Calico Enterprise, which is a self-managed security and observability platform that businesses and organizations can use to manage their applications and resources in containers, Kubernetes, and even the cloud.
  • Calico Cloud which is a next-generation Kubernetes-native cloud service that extends the declarative nature of Kubernetes while acting as a software as a service (SaaS) platform that allows for immediate response to security threats with flexibly priced packages

Tigera Calico Enterprise

Tigera’s Calico provides optimum security and observability for businesses and organizations to manage their resources, ensuring that the tools and security and compliance policies are administered over multi-cluster, multi-cloud, and hybrid deployments while also ensuring transparency, observability, and troubleshooting. Calico, as a CNI (Container Network Interface), also supports the broadest range of data points on platforms such as Windows and Linux to leverage all the benefits of the platform while improving interconnectivity. Leading enterprises, including AT&T, Discover, Merck, ServiceNow, and HanseMerkur, employ Tigera’s products to maintain secure systems across different platforms.
When talking about container systems, Tigera Calico is a pioneer in scalable networking and network policy. Tigera Calico is an open-source project that aims to make cloud networks easier to manage, expand, and protect. Customers can get constant and rapid convergence times with excellent troubleshooting and network security with Tigera Calico.
Project Calico is an open-source project that’s maintained and developed at Tigera, and it’s one of the most widely adopted networking applications and network policy providers for Kubernetes, which has allowed it to be used in hundreds and thousands of clusters around the world. It is also the default out of the box solution within every major cloud provider hosting Kubernetes such as Amazon Elastic Kubernetes Service (Amazon EKS), Google Kubernetes Engine (GKE), Azure Kubernetes Service (AKS), IBM Cloud Kubernetes Service (IKS), and it is also included in some of the widely used distribution of Kubernetes including Mirantis, Docker, Rancher, and many more.
Calico Enterprise builds on the Calico core to deliver more advanced network security solutions and provide tools that you would need to take Calico and help operationalize the network security and compliance for your entire Kubernetes platform. From a policy perspective, that means it helps their customers adopt best practices around Zero Trust and the least privilege approach to next network security while also focusing on enforcing policies at layer three and layer four by accounting for TCP and UDP traffic all the way up to layer seven by monitoring DNS policies as well.
Tigera’s Calico Enterprise has a lot to offer when it comes to navigating different systems in a variety of organizations as it provides:
  • The industry standard for K8s security and observability
  • Hybrid, Multi-Cloud, On-Premises integrated support
  • Centralized monitoring and management
Project Calico is a community-driven open-source project with a successful development and user base. Calico Open Source is an amalgamation of this initiative and is now the most extensively used networking and security solution for Kubernetes, with more than 1.5 million nodes running on a daily basis in 166 countries.
Calico Enterprise is a self-managed Kubernetes security and observability platform built on a Kubernetes-native architecture that extends Kubernetes’ declarative nature by allowing security and observability to be specified as code. This guarantees that security regulations and compliance are consistently enforced and provide observability for troubleshooting across multi-cluster, multi-cloud, and hybrid deployments.
Containers and microservices make up cloud-native apps, which have direct access to cloud and legacy applications. Microservices and containers in Kubernetes clusters are invisible to typical perimeter-based security solutions. Furthermore, because microservices are very dynamic and transient in nature, any security control based on a static IP address is as a result ineffective as they require dynamic security solutions. There are many impressive features of the Calico Enterprise solution that can be used to manage data and network security when using Kubernetes, including:

Secure Access Control

Secure connections to the outside of the cluster (DB, Data Center, SaaS) and at the Kubernetes Pod level are supported.

Visibility and Troubleshooting

Visualize and analyze connectivity difficulties in the K8s environment by following the flow.

Enterprise Security Controls

Apply your enterprise security policies to the K8s environment and monitor their compliance for homogeneity of information

Extend Firewalls to Kubernetes

By connecting existing firewall policies with K8s, security policies may be operated together through a single policy.

Zero Trust Security

Stay secure by implementing in-depth security measures such as workload authentication, authorization, and granting least privilege access

Intrusion Detection (IDS)

IDS support when using Kubernetes can facilitate in monitoring abnormal behavior and generating alerts in case of any unauthorized access attempts

Cloud Micro-segmentation

The Unified Segmentation Policy can be effectively applied in a static or dynamically mixed host and container environment.

Self-Service Security

There is a degree of customization involved as each team member automatically creates their own security policy as a code to ensure they can access the service safely

Unified Control

Provides unified network security across Multi-Cloud, Multi-Cluster, and Hybrid Cloud platforms

Zero Trust Security Like No Other

The impact and evolution of security in the digital landscape has transformed entirely. Security was initially based on Trust and specified parameters. For example, all physical and digital assets were maintained within the confines of a specific location, whether it was an office or a government facility. The systems maintained an infrastructure that was often connected via an intranet, but the development of the Internet and the functionality it offers allowed these local networks to join the online platform via the cloud and other technology to make the best use of shared resources and interconnectivity. This transition allowed data, technology, and infrastructure to move outside the parameter that required the security models to be reassessed. In Zero Trust, there need to be appropriate safeguards in place to verify users from remote locations and not from within a specific parameter.
The foundation of Zero Trust security arises from always verifying user identity to grant or revoke access to certain information depending on need and authorization clearance. The security authorization can be provided or removed at any point to protect the integrity of the system in case there has been a breach. Zero Trust is both a mindset and a methodology. According to the National Security Agency’s guidelines, it assumes that a breach is inevitable or has likely already occurred, so it constantly limits access to only what is needed. The zero-trust mindset includes four components which are also called the four A’s
  1. An aggressive approach to monitoring, management, and defense
  2. Assuming that all resource requests and traffic may be malicious
  3. Assuming your systems and devices already compromised
  4. Accepting that whenever you let someone end this access inherently opens the door to risk
Putting the zero trust mindset into practice requires the right user to be logged into the right laptop with appropriate credentials and them having access to the right application. This method frequently employs zero trust technologies such as identity access management, security, micro segmentation, web gateways, and next-generation firewalls, but we all know that criminals can gain access to our laptops or convincingly impersonate an employee, so it’s critical to keep an eye on how people’s devices are behaving and intervene if they appear to be acting suspiciously by limiting access.
Zero Trust security is a robust security theory that states networked entities should not be trusted by default, and therefore you should act as if your application or infrastructure has been hacked and is actively hosting malware. Zero Trust policies rely on real-time transparency into workflows, and they can only work if companies can continually monitor and confirm that requested connections have the appropriate capabilities and attributes to ensure they are secure. As threats and connection properties are all subject to change, a one-time validation will not suffice, and it requires constant updating. Zero Trust is essential for security compliance as it ensures that all access requests are thoroughly reviewed before authorizing connectivity to any of your corporate or cloud assets.
Because of the open nature of cluster networking, Kubernetes is particularly vulnerable to malware dissemination. By default, every pod can link to any other pod, even across namespaces. Without a security approach like Zero Trust, detecting malware or its proliferation within a Kubernetes cluster is incredibly difficult. This inspired Calico to create a Zero Trust environment by combining three key features:
  • encryption
  • least privilege access controls
  • defense-in-depth
Zero Trust Security offers some exciting features to enhance your information and network safety. The system:

Protects sensitive information and facilitates compliance

It ensures compliance with business and regulatory data protection regulations that demand encryption, such as HIPAA, PCI, GDPR, and SOX

Unauthorized access is automatically blocked.

By default, least privilege access control blocks all network traffic, allowing only approved connections to be executed

Self-service policy modifications empower developers.

Helps shift-left teams maintain the security posture required to meet legislation or your own internal security team’s compliance requirements, allowing you to go to production faster.

Security For Everyone

Tigera’s Calico Enterprise Zero Trust Security is designed to cater to a wide network of customers ranging from the private to the public sector. Take a look at how your business, enterprise, or government entity can benefit from the security features Tigera has to offer.

Commercial Enterprises

Commercial enterprises and organizations must evolve with the times, and Kubernetes is the future to building scalable modern applications to enhance customer experience and business functions. The ease of using K8 apps comes with the need to implement safeguards for monitoring and securing Kubernetes applications without impacting their availability. Tigera’s Calico Enterprise offers a cost-effective solution to manage security threats and access control modules when using Kubernetes to automate and manage different applications essential for the functioning of the business.

Government Entities

Government organizations process large data stores of information through software and applications stored on local systems, making it challenging to keep up with the latest technological advancements. This process can be especially debilitating to departments that need the latest technology to keep the country running smoothly and efficiently, such as the Department of Defense, which prompted them to move to Kubernetes. However, another major issue arose relating to security and access protocols on an open-source network which is why Zero Trust Security principles need to be adopted throughout both north-south and east-west traffic. Tigera’s Calico Enterprise is readily available to manage the security risks associated with government departments to allow their systems to remain updated and vigilant.
