You can find plenty of rapport horror stories with a quick Google, so I thought I might just pick at Trusteer's own literature for grins.

Rapport is a lightweight security software solution that protects web communication between enterprises, such as banks, and their customers and employees.
My first encounter with Rapport was when somebody brought a domain laptop to me with concerns that it might have malware on it. I was inclined to agree when I saw IE locking up, a modified address bar and generally running like molasses.

Rapport implements a completely new approach to protecting customers and employees. By locking down customer browsers and creating a tunnel for safe communication with the online website, Rapport prevents Man-in-the-Browser malware and Man-in-the-Middle attacks. Rapport also prevents phishing via website authentication to ensure that account credentials are passed to genuine sources only.
Um, SSL and trusted certificates?

Rapport’s unique technology blocks advanced Trojans including Zeus, Silon, Torpig and Yaludle without the need to constantly update and chase the different variants of these Trojans. Its proprietary browser lockdown technology simply prevents unauthorized access to information that flows between customer and employee websites regardless of whether these attempts were generated by new or known Trojan variants.
That is a bold, bold claim. In their own words,
Rapport blocks advanced Trojans without the need to constantly update and chase the different variants of these Trojans. It seems every other security software vendor is using the wrong model. But wait...

Advanced automatic update mechanisms allow Trusteer to react immediately to new threats.
So.... which is it? Column A or column B?

Trusteer’s technology protects the weakest link in the online banking security chain – the browser.
Says Trusteer, and almost nobody else. The browser
is a security concern but it's nowhere near the top of the list.

Rapport is based on... proprietary security technologies that can easily scale to protect customers and employees against the rapidly growing threat of malware and online fraud. Its lack of dependence on heuristics or signatures ensures this scalability.
Oh, so maybe it is column A after all.

Rapport locks down all programmatic interfaces to sensitive information inside the browser while it is connected to a protected website. Additionally, Rapport protects the browser's memory and prevents any pieces of code injected into the browser's memory from capturing or modifying sensitive information.
Only after it has encouraged a user to install a piece of software they didn't ask for off the internet with admin rights, otherwise you just get the watered down user land variant.
If running Rapport makes you feel safer and causes you no issues, then by all means carry on. To be fair, I hardly get problems specifically with Rapport these days so maybe they have sorted out some of the stability issues.
However, in my opinion, the concept itself is so flawed I couldn't honestly recommend it to anybody.
