We have provided cloud solutions to asset managers for the past three years and in this time completed various types of email migrations to Office 365. These migrations include a mix of moving clients from an on-premise Exchange or a third-party legacy private cloud provider entirely to Office 365 to working with hybrid solutions that span both own on-premise and Office 365. 

During these migrations we noticed a range of issues with clients who opted to set up their Office 365 accounts via a more economical re-seller or through bundled packages with other services. 

Here are a few things to be wary of when setting up your Office 365 accounts with the wrong partner:

  1. Some of these providers offer what is called a “Syndication Tenant”. Microsoft retired this type of subscription but it is still offered by many existing re-sellers. With a Syndication Tenant agreement, the Office 365 account, Azure AD tenant and data is held by the re-seller and can’t be easily migrated away. In this setup, a multiple step process is required to hand over the account to another partner. The data needs to be backed up, the account deleted, and the data re-imported into a new account. All of this means extra complexity, user upheaval and extended downtime. 
  2. Some re-sellers, especially the syndicated tenant providers, do not offer the account holder true admin rights which means only a subset of the Office 365 functionality and management is available. 
  3. You could end up locked into a strict contract when negotiating your agreement. Sometimes your contract could last up to two or three years with no variations possible on the user services and license counts. 
  4. Security options are limited when compared to native Office 365 solutions or conditional access policies.
  5. Interface solutions from these re-sellers often lack basic functionality such as single sign on tools. 

With issues like these it is important to do your due diligence when exploring your options before committing. More likely than not you will find that your safest and most efficient option is to partner with a trusted and experienced service provider or go to Microsoft directly.

How Hentsū does it differently

We are a Tier 1 Microsoft Cloud Service Provider (CSP) and work directly with Microsoft. We are also a Silver partner and specialists in the asset management industry. All of this allows us to provide a range of flexible solutions tailored to the world of fund management. 

A good time to reach out to us is when your fund is about to be registered (SEC, FCA, etc). We know the industry requirements and can provide guidance on best practices and compliance. We also have the ability to work earlier with startups to ensure that they have all the tools in place from day one and can scale as they grow. 

Generally, we advise to take the following steps when setting up cloud services: 

  • Create a native Office 365 account through Microsoft directly, or use one of the Hentsū starter packages. We create client accounts directly with Microsoft so you hold the keys to the Azure AD tenant.  Your data is always your data so you can migrate to another provider at any time.  
  • Validate that you hold ownership over your Office 365 account and email domain. 
  • Purchase license subscriptions and set up users and groups.
  • Don’t go for 12 month commitments until you are sure of which services you actually need. We offer all of our clients the same 12 month discounts but on a monthly rolling basis. 
  • Set up data loss prevention and data retention policies and be aware of two factor authentication and mobile device security. We enable all these features by default as you on-board to our setup.

So be sure to carefully consider all the possibilities before signing on with Office 365 re-sellers or bundled solutions, as there are a range of options for your Office 365 needsIf you are unsure of where to go next for your Office 365 solutions, reach out today to learn how we can best support you.

Cloud Hosted Email and Collaboration

Hentsū provides cloud solutions to the hedge fund and asset management industry. We are partners with AWS, Microsoft and Google, and have to be agnostic when it comes to the choice of cloud platforms. However, we also need to be analytical and to choose the right solution for a customer challenge. Recently we had a number of clients come on board with the G Suite, and a number of discussions around moving to/from G Suite and Office 365.
"Which one is better, G Suite or Office 365?"
To help us understand the differences better, as well as summarise them for our clients, we put together a comparison of the two. We dug into our past experiences with migrations, as well as our current client base and how they are using the two platforms.

Google G Suite

If you are a Gmail user and love how Google revolutionised email, there is a natural tendency to love the broader G Suite. Google launched their offering back in 2006, then known as Google Apps. It is a robust platform, slick user-friendly interfaces, rapidly evolving features, and with some clever AI. From our client experience, we have found G Suite to be favoured by startup funds, especially quant funds and users bringing their experience over from academia. On the entry packages it is extremely affordable for the functionality it provides.

Microsoft Office 365

Microsoft was relatively late to the game of cloud hosted collaboration and office applications. For many years Microsoft had its focus on the Windows desktop and the Office applications it sold for that desktop experience. It has since made huge strides towards cloud applications and platforms. It is also unique in that it extends its desktop application footprint with its cloud packages. The Office 365 offerings come with licenses to use the desktop applications, also on mobile devices.

Feature Comparison

We compiled a number of categories to compare the two platforms. This is by no means an exhaustive comparison, but it is one which we tailored to our hedge fund market experience, regulatory and security requirements, and user mobility. We covered these categories:
  • General service features such as security, resilience, storage limits and support
  • Basic collaboration and office application functionality
  • Security and compliance features, such as multi factor authentication, data loss protection, and encryption
  • Mobility and usage of the applications across mobile devices
We also included some of the entry level packages from G Suite, purely to highlight what is not included with them. We have had a number of startup funds come along with the entry level G Suite products, which will only work up to a certain level. Once a fund grows, after which G Suite Enterprise is a far better choice and this is our recommended package for any hedge funds. We have included only the Microsoft Office 365 E3 package for comparison as this is the core offering of all Hentsu cloud products and services. There are more economical packages, but again not what we would recommend for hedge funds. We have tried to avoid getting into details around the interface, and to minimise subjective analysis. We recognise that there are some significant differences between the two interfaces, and at times hugely personal affections with one or other. However, it is also necessary to cut through the external view and look at what is functionally available, what is overall best for the firm and all its users. We included a price comparison only as a general steer, this is not a TCO type analysis.

We have worked with both G Suite and Office 365 for many years. Nonetheless, it was surprising to actually see spelled out how far Office 365 has come in recent years. Another surprising element is how much Microsoft has managed to offer with their cloud platform what was traditionally considered only enterprise-ready when done on-premise. The entry level G Suite Basic and Business packages fall far short of what would be usable in a security conscious and regulated firm. The are significant gaps when it comes to security and auditing, which would require complexity and investment in third party products to mitigate. Hentsū would recommend G Suite Enterprise for a firm with financial regulations and security requirements. The battle of features between G Suite Enterprise and Office 365 E3 is a far more interesting. Office 365 has some obvious advantages, such as licensing for Microsoft Office across a range of devices is included in the price and its offline capabilities. There are some less obvious advantages, and these were highlighted for us recently. For example with S/MIME end to end encryption Office 365 is the clear leader here, and it is far more capable to be locked down to create a security sandbox similar to on-premise.
