API Management and Security
This Leadership Compass provides an overview of the market for API management and security solutions along with recommendations and guidance for finding the products which address your requirements in the most efficient way. We examine the complexity and breadth of the challenges to discover, monitor and secure all APIs within your enterprise and identify the vendors, their products, services and innovative approaches towards implementing consistent governance and security along the whole API lifecycle.
From what used to be a purely technical concept created to make developers’ lives easier, Application Programming Interfaces (APIs) have evolved into one of the foundations of modern digital business. Today, APIs can be found everywhere – at homes and in mobile devices, in corporate networks and in the cloud, even in industrial environments, to say nothing about the Internet of Things.
APIs allow developers to create applications faster by enabling support for modern architectures like microservices. They ensure that applications from different vendors can exchange data seamlessly, orchestrate massive cloud infrastructures and global networks of smart devices. They enable business communications with suppliers, service providers, and customers. APIs can also unlock numerous new business models for companies to offer their core services in innovative ways, to reach new customer bases or to streamline sales and services across multiple channels.
As companies are struggling to maintain their business agility, to react to the ever-changing market demands and technology landscapes, the need to deliver a new application or service to customers as quickly as possible often trumps all other considerations. Rapidly growing demand for exposing and consuming APIs, which enables organizations to create new business models and connect with partners and customers, has tipped the industry towards adopting lightweight RESTful APIs, which are commonly used today. The rapid adoption of REST APIs also coincided with the exponential growth of cloud computing and mobile device proliferation, where they were the perfect medium to enable integrations between these heterogeneous systems and facilitate data exchange on a massive scale.
In a world where digital information is one of the “crown jewels” of many modern businesses (and even the primary source of revenue for some), APIs are now powering the logistics of delivering digital products to partners and customers. Almost every software product or cloud service now comes with a set of APIs for management, integration, monitoring or a multitude of other purposes.
As it often happens in such scenarios, security quickly becomes an afterthought at best or, even worse, it is seen as a nuisance and an obstacle on the road to success. The success of an API is measured by its adoption and security mechanisms are seen as friction that limits this adoption. There are also several common misconceptions around the very notion of API security, notably the idea that existing security products like web application firewalls are perfectly capable of addressing API-related risks.
When the previous edition of our Leadership Compass was published, our research clearly indicated that the market for API management solutions was undergoing rapid growth, marked by a wave of acquisitions. This tendency has continued in the recent years as well. However, the more important trend is the growing awareness of the critical role of security in API management solutions. KuppingerCole thus continues placing a strong emphasis on API security but expands the coverage of this Leadership Compass to incorporate every step of the API lifecycle. Only by combining proactive application security measures for developers with continuous activity monitoring and deep API-specific threat analysis for operations teams and smart, risk-based and actionable automation for security analysts one can ensure consistent management, governance and security of corporate APIs and thus the continuity of business processes depending on them.
1.1 Market Segment
We have long recognized API Economy as one of the most important current IT trends. Rapidly growing demand for exposing and consuming APIs, which enables organizations to create new business models and connect with partners and customers, has tipped the industry towards adopting lightweight RESTful APIs, which are commonly used today.
Unfortunately, many organizations tend to underestimate potential security challenges of opening up their APIs without a security strategy and infrastructure in place. Such popular emerging technologies as the Internet of Things or Software Defined Computing Infrastructure (SDCI), which rely significantly on API ecosystems, are also bringing new security challenges with them. New distributed application architectures like those based on microservices, are introducing their own share of technical and business problems as well.
Creating a well-planned strategy and reliable infrastructure to expose their business functionality to be consumed by partners, customers, and developers is a significant challenge that has to be addressed not just at the gateway level, but along the whole information chain from backend systems to endpoint applications. It is therefore obvious that point solutions addressing specific links in this chain are not viable in the long term, and KuppingerCole’s analysis is primarily looking at integrated API management platforms, but with a strong focus on security features either embedded directly into these solutions or provided by specialized third party tools closely integrated with them.
When the previous edition of the Leadership Compass on API security was published, the industry was still in a rather early emerging stage, with most large vendors focusing primarily on operational capabilities, with very rudimentary threat protection functions built into API management platforms and dedicated API security solutions almost non-existent. In just a few years, the market has changed dramatically.
On one hand, the core API management capabilities are quickly becoming almost a commodity, with, for example, every cloud service provider offering at least some basic API gateway functionality built into their cloud platforms utilizing their native identity management, monitoring, and analytics capabilities. Enterprise-focused API management vendors are therefore looking into expanding the coverage of their solutions to address new business, security or compliance challenges. Some, more future-minded vendors are even no longer considering API management a separate discipline within IT and offer their existing tools as a part of a larger enterprise integration platforms.
On the other hand, the growing awareness of the general public about API security challenges has dramatically increased the demand for specialized tools for securing existing APIs. This has led to the emergence of numerous security-focused startups, offering their innovative solutions, usually within a single area of the API security discipline.
Unfortunately, as the diagram below illustrates, the field of API security is very broad and complicated, and very few (if any) vendors are currently capable of delivering a comprehensive security solution that could cover all required functional areas. Although the market is already showing signs of undergoing consolidation, with larger vendors acquiring these startups and incorporating their technologies into existing products, expecting to find a “one stop shop” for API security is still a bit premature.
Although the current state of API management and security market is radically different from the situation just a few years ago, and the overall developments are extremely positive, indicating growing demand for more universal and convenient tools and increasing quality of available solutions, it is yet to reach anything resembling the stage of maturity. Thus, it’s even more important for companies developing their API strategies to be aware of the current developments and to look for solutions that implement the required capabilities and integrate well with other existing tools and processes
