Citrix Gateway plugin doesn't function with macOS Big Sur (macOS 11.x)

Citrix Leave a comment

Citrix recommends the use of Citrix SSO for VPN access for macOS. For product documentation, please see https://docs.citrix.com/en-us/citrix-gateway/citrix-gateway-clients/gateway-clients-feature-parity.html

Note : Citrix SSO app cannot be launched from browser. It has to be launched natively by the user i.e open the app manually and connect to a vserver. This is a change in behaviour from Citrix Gateway plugin which could be invoked from browser when the user enters the address of the vserver in browser.

Citrix Endpoint Analysis plugin (EPA plugin) for macOS will continue to work as it doesn’t use Kexts.

Enterprise blockchain bytes: R3 and IBM collaboration and Calastone acquisition

PCIS Support Team Leave a comment

Blockchain technologies for the enterprise continue to see various updates. IBM and R3 have announced a collaboration to bring the latter’s enterprise blockchain platform to IBM, while the acquisition by The Carlyle Group of a majority stake in Calastone has put a focus on its distributed market infrastructure (DMI).

R3 has announced a new open beta program to bring Corda Enterprise to IBM LinuxONE, delivered via IBM Cloud Hyper Protect Services, with general availability expected in the first quarter of 2021. IBM is also establishing an R3 centre of excellence, looking to provide services to IBM clients that have – or plan to adopt – R3 solutions.

“Enterprises, especially those in regulated industries, are increasingly looking to build blockchain solutions with advanced security and data privacy features while addressing performance,” the two companies wrote. “For clients with highly sensitive data and workloads such as digital identity, digital assets, central bank digital currencies, tokens, payments information, or smart contracts being spread across hybrid cloud environments, IBM LinuxONE provides a highly secured platform certified to meet the highest level of security certification commercially available.”

The partnership makes for interesting strategic reading. Hyperledger, hosted by the Linux Foundation, has predominantly been IBM’s primary offering; indeed, IBM Blockchain Platform is its commercial deployment of the open source Hyperledger Fabric. To date, R3’s Corda has been seen as a competitor in the enterprise blockchain space.

IBM said the move would ‘complement’ its excisting blockchain services and offerings ‘to bring even more choice to the market.’

“Blockchain is fast emerging as the technology of choice to drive digital transformation and R3 and IBM will provide access to the privacy and security inherent in blockchain technology underpinned by IBM LinuxONE,” said David E. Rutter, CEO of R3. “This combined with the deeply knowledgeable team within IBM Services’ new R3 centre of excellence, can empower customers to level up their digital transformation drive.”

Elsewhere, The Carlyle Group has agreed to buy a majority stake in Calastone. The global funds network introduced its distributed market infrastructure (DMI) last May to enable full automation and digitalisation of the fund transaction process through distributed ledger technology.

Julien Hammerson, chief executive officer of Calastone, said there was ‘huge potential for growth based on the technology platform and unique service offering created.’

During September, Hyperledger, an open-source effort created to advance cross-industry blockchain technologies, added eight new organizations, including Chainstack, SIMBA Chain, SIX Digital Exchange, and Visa.

The company announced the news at their annual Member Summit, September 9.

“In a year that has looked like no other, Member Summit is an even more important grounding point for our community,” said Brian Behlendorf, Executive Director, Hyperledger. “The pace of adoption for enterprise blockchain is accelerating, and our members are a driving force for critical new technologies and solutions. Our latest members will be important new voices as we set agendas and roadmaps that will keep us pushing this market forward in the year ahead.”

When asked what was on the horizon for Hyperledger in 2021, Behlendorf said he expects continued growth in digital identity, potentially with vaccination records and digital recordkeeping. Behlendorf said. “As a project, we have benefited from a broad greenhouse strategy testing new pilots and other active projects, working to develop new standards in multiple industries. Our membership continues to be solid and growing.”

Hyperledger also announced seven more companies, Creativehill, DeepDive Technology Group, NEC, SAP, SwissCom, Tech Mahindra and Tencent, have completed the training requirements to become Hyperledger Certified Service Providers (HCSPs). This brings the total number of HCSPs to 18.
