For a small or medium-sized business (SMB), signing a deal with their first enterprise customer is a big deal. Going upmarket is frequently a goal and sometimes a necessity for B2B SaaS vendors, but it isn’t easy. 

In addition to ensuring your core features meet the needs of enterprise buyers, you also have to satisfy a long list of additional requirements in other areas like security, compliance, and scalability—all of which identity plays a crucial role in. While the needs of SMB customers may have been met with straightforward authentication, authorization, and identity management features, enterprise decision-makers expect much more.

In this guide, we will walk through the identity requirements and the ancillary functionality that enterprises need while highlighting what you — the B2B SaaS vendor — need from your customer identity implementation to scale your business sustainably.

Public Sector Infographic: Secure, Frictionless CIAM in the UK

Secure, Frictionless Customer Identity and Access Management

Customer identity and access management (CIAM) helps public sector agencies achieve secure, seamless, frictionless interaction that builds trust with citizens. To assess trends in CIAM adoption in the United States (US), United Kingdom (UK), and Australia and New Zealand (ANZ), Auth0/Okta partnered with Market Connections to identify and quantify how government agencies at all levels are providing digital services. The study specifically looked at the current state of identity authentication and security; challenges to current implementation; current pain points; and plans and concerns about changing systems and processes. These data points highlight key findings.

From improving customer experience through seamless single sign-on (SSO) to making multi-factor authentication (MFA) quick and easy, your login box must find the right balance between user convenience, security, and privacy. 

In fact, we believe that the companies that will succeed in the next five years will be the ones best-equipped to meet the ever-growing consumer expectations for these three attributes. But what will that future look like, and by what path can today’s companies become tomorrow’s leaders?

In this ebook, we will answer these questions and take a closer look at the future of authentication, and the impacts of passwordless.

CIAM for Dummies

Download this free guide to find out:
- What CIAM is and why it matters
- What capabilities and features to look for in a modern CIAM solution
- Ten steps to implementing the right CIAM solution for your business

Usernames and passwords have become a part of everyday life. Consumers manage different accounts for online shopping, bank accounts, and mobile apps. This is customer identity and access management (CIAM), and you no doubt recognize some of the differences between good CIAM and bad CIAM in many of your digital experiences. For example, your mobile banking app may give you a strong sense of security and ease of use by simply authenticating you with a fingerprint or face scan. On the other hand, you’ve likely abandoned more than one online shopping cart when a retailer wants you to complete a lengthy registration process. Registration can take more time than finding the products you were looking for!

Ever wondered how blockchains work? Or how Bitcoin managed to change the landscape of monetary transactions? Or what's the magic behind Ethereum?
Then this e-book is for you. In it we delve into the development of blockchains: distributed, immutable, verifiable ledgers for transactions.
We explore how they became instrumental in the development of the first large-scale cryptocurrency, Bitcoin, and how its ideas were extended to give birth to Ethereum, a powerful blockchain that marries decentralized transactions with Turing-complete contracts.

What you need to know about:
1. Building IAM
2. Buying IAM
3. Doing both


__A Better Way to Implement Identity and Access Management:__
State and local government organizations traditionally faced a tough choice on access management tools: Build it yourself or buy it off the shelf from a third-party vendor? In this infographic, see how organizations today can do both.

Gartner Peer Insights Ebook Auth0

I. What Is Access Management?
II. What Is Gartner Peer Insights “Voice of the Customer”?
III. What Is the Gartner Peer Insights Customers’ Choice?

In April 2021, Auth0 was recognized with Gartner Peer Insights’ Customers’ Choice distinction for Access Management. The recognition, along with the review criteria for the distinction, are found in Gartner’s annual Voice of the Customer document. This eBook discusses what Gartner Peer Insights and its recognitions are, as well as highlights Auth0’s placement. 

Gartner Peer Insights Customers’ Choice constitute the subjective opinions of individual end-user reviews, ratings and data applied against a documented methodology; they neither represent the views of, nor constitute an endorsement by, Gartner or its affiliates.

Três tipos principais de ataques

Infográfico: Três tipos principais de ataques

Lançado como parte do primeiro [relatório Estado da Identidade Segura](https://auth0.com/resources/whitepapers/state-of-secure-identity-report-pt) da Auth0, este infográfico revela os 3 principais ataques que ameaçam a segurança das identidades.

Lançado em junho de 2021, o Relatório Estado da Identidade Segura da Auth0 revela insights das nossas próprias tendências e análises para ajudar a definir o espaço de segurança da identidade, explicar as novas ameaças e fornecer estratégias concretas para mitigação.

Para uma análise mais aprofundada, leia o [relatório Estado da Identidade Segura](https://auth0.com/resources/whitepapers/state-of-secure-identity-report-pt) completo e saiba mais sobre:
- Preenchimento de credenciais
- Ataques de injeção
- Criação de contas falsas
- Ataques de desvio de MFA
- Medidas defensivas sendo adotadas para combater esses ataques
