February 28, 2017Our promise to the industry was to engage, educate and provide valuable insight into major cybersecurity issues facing organizations around the world.
Here is a small recap of what happened at RSA Conference, so you can feel like you were able to attend:
Moment 1: ‘Cyber Resilience Think Tank’ at the San Francisco NASDAQ Center
The Mimecast team hosted a great event at the San Francisco NASDAQ Center for an early morning ‘Think Tank’ lead by Mimecast’s CTO, Neil Murray, and moderated by Venable’s CEO, Ari Schwartz. Security thought leaders from various industries joined in one room to network and share the challenges organizations face today with cyber resilience. As organizations work to become adopt a more cyber resilient strategy there was consensus among the peers in the room that the diversity of the attack must equal the diversity of the defense.
Moment 2: Dark Reading Interview with Bob Adams
Lights, camera, action! What a moment for our very own senior cybersecurity strategist, Bob Adams, who was in front of the camera for an interview with Dark Reading. Bob highlighted the latest security gaps with internal email and the proposed solution, which Mimecast launched at the start of the show. He also discussed how to gain valuable insight into the attacks being missed by many incumbent email security solutions. Interested in watching? Click on the image to watch the full interview below
Moment 3: Live Hacks at the Mimecast Booth
Full house, no problem. Security experts Bob Adams, Julian Martin, and Matthew Gardiner demonstrated onsite ‘LIVE HACKS.’ The gist of the hacks incorporated social engineering attacks, phishing attacks and the ease at which a hacker can use email as a primary hacking mechanism to own the target’s system, gain bank information and take over someone’s video camera without them knowing. You can view the live Periscope video below if you would like to take a look for yourself.
Moment 4: Insights into the latest Cyber Threat Plaguing email
Who doesn’t like working on solving problems with clients? At the event, we got to meet with many customers and new prospects. Thank you, to everyone who stopped by the booth. We were able to share the latest email security threats we see organizations face daily. This included 421 unknown malware threats, all of which were missed by a number of incumbent email security solutions. Check out a summary of these threats in our latest Email Security Risk Assessment infographic we had posted in the booth here.
February 22, 2017Crippling financial penalties and strict new privacy rules have grabbed most of the EU General Data Protection Act (GDPR) headlines so far. This is no surprise, given the sweeping nature of the act, but ahead of the May 2018 implementation date, it’s important to look at some of the more detailed compliance requirements, especially for email.
A key tenet of the GDPR – that organizations must respond in a timely manner to Subject Access Requests (SARs), inquiries from EU residents about the location and processing of their personal data, as well as to requests that it be erased – will likely force a sea-change in how organizations manage all data, personal or otherwise.
In the meantime, little’s been said about the challenges of overhauling privacy in the current era of phishing and ransomware. The two developments – growing regulatory burdens and the increasingly volatile threat landscape – put organizations in a double bind. The GDPR emerged in part as a response to the growing cybercrime threat, yet its directives to retool organizational policies, processes and structures stand to compound the burdens of well-intentioned organizations.
To manage the dual risks of GDPR compliance and cybercrime, you need to focus on email security and governance. Here are some guidelines for formulating such a strategy:
Review your email infrastructure
Over 90 percent of phishing cybercrime exploits begin with email, making it the single biggest threat vector to organizations and the data they manage. Furthermore, not only are emails a common vehicle to share and exchange personal data, email servers are prime repositories for such data as names, email addresses and associated contact information.
Managing GDPR risk starts with securing your data and infrastructure against the litany of email threats mentioned above.
Implement strong search and e-discovery
To suit GDPR mandates for reporting on and deleting personal data upon request, your email infrastructure needs to streamline search and e-discovery. A robust complement of case management tools – early case assessment, search and saved search, legal hold application, retention adjustments, and export, to name a few – will also expedite your ability to respond effectively to requests.
Educate and inform your mailbox holders
One careless click can undermine even the most capable security or governance infrastructure. This makes social engineering exploits such as phishing and impersonation attacks so devastatingly effective. A well-informed workforce is an essential component of an effective GDPR compliance strategy. Every user in your domain must be vigilant against the onslaught of email-based attacks, and play a vital role in notifying your Data Protection Officer (DPO) of any suspected privacy breaches.
Bear in mind that the guidance above addresses compliance issues related specifically to email. To manage GDPR, you’ll need to transform your privacy and governance operations wherever personal data is stored or processed: customer records, databases, CRM systems, and ERP platforms, etc. But chances are good you’ve already considered these repositories; it’s email that’s often overlooked in the compliance conversation. In reality, nearly all email servers and archives contain personal data.
No matter where your organization is based, if you manage or process personal data associated with EU residents, you will be impacted by the GDPR. Managing against GDPR penalties involves securing and tightly controlling your email servers and archives. The countdown to prepare has begun.

Would it surprise you to learn that in recent testing Mimecast has seen a 13.2% false negative rate for incumbent email security systems? Does your current email security system let through an inordinate amount of spam, malware, malicious URLs, or impersonation emails?
How would you find out if it did? Is your primary source for detecting false negatives your users? Do you wonder how your email security performance compares with your peers?
The fact is, until now, there hasn’t been much data comparing or benchmarking the performance of email security systems. They all claim the ability to defend against spam, malware, spear-phishing, malicious links and other email attack techniques. But how good are they really? How do they compare in their ability to block opportunistic email-borne attacks as well as more targeted attacks?
In working with our more than 25,000 customers, Mimecast has seen firsthand that email security systems do not perform equally well. To address this lack of data head-on, Mimecast launched its Email Security Risk Assessment (ESRA).
The Mimecast ESRA has three goals:
- To test the Mimecast cloud security service against an individual organization’s incumbent email security system. To help the organization see in one report the number, type, and severity of email-borne threats that are currently getting into their organization.
- To inform the security industry with hard data on the effectiveness of various commonly-deployed, email security systems.
- To inform the security industry with hard data regarding the number, type, and severity of email-borne threats that are actively being used in attacks.
In an ESRA, Mimecast uses its cloud-based Advanced Security service to assess the effectiveness of other email security systems. The ESRA test passively inspects emails that have been inspected by the organization’s incumbent email security system and received by their email management system. In an ESRA, the Mimecast service re-inspects the emails deemed safe by the incumbent email security system and thus looks for false negatives, such as spam, malicious files, and impersonation emails.
The results we’ve uncovered so far are concerning: Email attacks ranging from opportunistic spams to highly-targeted impersonation attacks are getting through incumbent email security systems both in large number and in various types.

If you equate internal threats with just malicious insiders you need to read on. When thinking of the people behind internal threats you need to be concerned about three profiles, not just one:
- Compromised Insiders: These employees have had their accounts or systems taken over by an external attacker through credential harvesting, phishing or the installation of various forms of malware. While many of these takeovers are initiated via email, web drive-bys, botnets, and other modes of entry can also be the source of the compromise.
- Careless Insiders: There are also employees at every organization who ignore or simply don’t fully understand the organization’s security policies and rules. We call these folks, Careless Insiders. While ignoring security policies is not done with malicious intent, the actions – such as sending sensitive information insecurely or to the wrong people – can put the organization at greater risk of sensitive data leakage or attack.
- Malicious Insiders: And last but not least, are the Malicious Insiders. Though not common, malicious insiders do exist, and when they strike can cause significant damage. These rogue employees either intend to profit personally from or do damage to the organization by stealing, leaking or compromising confidential data or systems.
So, which one is the real problem? Unfortunately, the answer is all of them! In a recently published survey and report from Forrester, respondents were asked whether their organizations had had security incidents from each of the three types of insiders over the last 24 months. The answering was sobering: 63%, 57%, and 41% respectively had incidents from each type, respectively – Compromised, Careless, and Malicious. Clearly, internal threats are really threatening and not as rare as one might hope.
To more fully address the security threats represented by the each of these internal threat profiles, Mimecast recently announced the latest addition to our Mimecast Target Threat Protection security service: Internal Email Protect. Internal Email Protect provides for the scanning of attachments and URLs for internal-to-internal emails as well as content filtering enforced by Data Leak Prevention services. It also includes the ability to automatically delete infected emails and attachments from employees’ inboxes. In addition, so that your organization doesn’t become an attack stepping stone to one of your partners or customers, Internal Email Protect also adds the scanning of attachments and URLs for your outbound emails. Even more exciting, Mimecast is the only cloud-based email security service that has this capability!
Unfortunately, internal threats are a fact of business life. But by adding Internal Email Protect to your implementation of Mimecast Targeted Threat Protection, this service can reduce the risk that your organization will be negatively impacted by them.
