Email Security SaaS

Email is the preferred communication medium for exchanging messages and file attachments due to it being so simple, fast, and inexpensive. As businesses exchange emails as part of their normal daily workflow, they continue to become more and more attractive targets for cybercriminals.

Inquest cloud and SaaS email security tool uses Deep File Inspection to analyze, identify, and prevent malware, phishing, ransomware, and more.
Email Security SaaS


Threat actor groups regularly launch sophisticated email phishing campaigns to lure company employees into downloading malicious file attachments that contain embedded malware or ransomware.  Successful campaigns lead to identity impersonation, fraudulent account creation, complete system lockout accompanied with a demand for a ransom to be paid or even system compromise resulting in the exfiltration of sensitive data.

Even the most advanced and popular email security solutions are trivial to evade and not enough to identify the tactics and techniques of today's sophisticated email-borne threats.


InQuest's integrated cloud email security solution, leveraging our patented, Deep File Inspection (DFI) engine, goes to unparalleled levels of scrutiny to analyze, identify, and ultimately prevent malware, phishing, ransomware, spam, and scams from being delivered to your users’ inbox.  We utilize machine vision and Optical Character Recognition (OCR) to identify sensitive information within scanned documents as well as other images used as attack lures.  Our cloud-based solution can be easily integrated with your existing Microsoft Exchange, GSuite or Microsoft Office 365 deployment in minutes, quickly enabling you to address the gaps in their defenses.  We provide real-time prevention of account takeovers, brand impersonation, email spoofing, sender forgery and social engineering campaigns.

Malware and Ransomware can be lurking in a variety of different file formats and objects.  InQuest uses a recursive file dissection engine designed to unwrap the layers of obfuscation employed by threat actors, which masks and protects their malicious code.  Our file dissection engine automatically unravels the evasion techniques used to hide this content.  Through these advanced analytical methods, we offer anti-spam, anti-phishing, anti-ransomware and advanced anti-malware capabilities that identify multiple detection points within an attack chain.

Our proprietary Deep File Inspection (DFI) engine is capable of decoding, decompressing, decompiling and deciphering file content, which provides unsurpassed visibility.  Ultimately exposing a myriad of additional context for analysis to aid in identifying and preventing threats as well as sensitive data-loss.  Our static analysis engine peers well beyond layer 7 of the OSI model, dissecting common carriers to expose embedded logic (macros, scripts, applets) and semantic context (e.g., cells of the spreadsheet, words in a presentation).

Business Email Compromise (BEC) Protection

It begins with the initial delivery of the email lure to the individual mailbox, covering the full spectrum of BEC phishing challenges, both technical and non-technical, from internal and external relationship building and profiling, to advanced content analysis and more, all in real-time.  The aggregation of this information creates a baseline of normal communications that are constantly analyzed to produce unique behavior patterns for every account.
