If there is some sort of secret society going on all the owners of large corporations would surely put a meaning into their logos?

My next lgo is that of a company who have an important role in our world.

Well WHO?

That's it, WHO. The World Health Organization.
This is a specialist organization of the UN.

A very interesting and detailed logo.

This logo would actually seem to have a less sinister logo - Depending on the symbols you look at.

The serpent alone is a very interesting symbol on its own. And being wrapped around a sword make WHO seem like a nice organization.

So, the serpent wrapped around the sword is a christian symbol.
It is know as ''The serpent lifted up''.
It means a sign of salvation coming from the old testament and mentioned in John 3:14.

2009 influenza pandemic Main article: 2009 flu pandemic Swine Influenza A/H1N1 In 2007, the WHO organized work on pandemic influenza vaccine development through clinical trials in collaboration with many experts. A pandemic involving the H1N1 influenza virus was declared by Director-General Margaret Chan in April 2009. By the post-pandemic period critics claimed the WHO had exaggerated the danger, spreading "fear and confusion" rather than "immediate information".[102] Industry experts countered that the 2009 pandemic had led to "unprecedented collaboration between global health authorities, scientists and manufacturers, resulting in the most comprehensive pandemic response ever undertaken, with a number of vaccines approved for use three months after the pandemic declaration. This response was only possible because of the extensive preparations undertaken in during the last decade".[103]

In common modern idiomatic usage it refers to a victory. The expression "resting on one's laurels" refers to someone relying entirely on long-past successes for continued fame or recognition, where to "look to one's laurels" means to be careful of losing rank to competition

This next company has a logo which is pretty normal and is hard to find much symbolism but I found a possible link.

Lets look at

American based agricultural multi-national corporation.

Just so you know, I am 100% doubtful that DOLE has any care for its customers or any associations. Money is key in this company.

I think it's important that you all know about DOLE as they have a pretty horrific back ground.
For a start

Throughout 2012, Dole Packaged Foods contributed $171,261 to a $46 million dollar political campaign known as "The Coalition Against The Costly Food Labeling Proposition, sponsored by Farmers and Food Producers" [34] This organization was set up to oppose a citizen's initiative, known as Proposition 37, demanding mandatory labeling of foods containing genetically modified ingredients. As a result, there is a growing boycott of their products across North America

SUN-SETTING: A symbol either of the termination, or the commencement, of the great cycle of life

Labor relations The banana industry has traditionally been dominated by a few large corporations, which employ low-wage workers in developing countries.[23][24] Dole was named as a defendant in a wrongful death lawsuit filed on behalf of 73 heirs of victims of paramilitary violence in Colombia.[25] In 2007, Nicaraguan plantation workers, represented by Los Angeles-based personal injury lawyer Juan Dominguez, sued Dole and Dow Chemical Company, claiming the use of illegal pesticides such as the now banned Nemagon (containing DBCP) had made them sterile. The pesticide was not banned in Nicaragua until after Dole ceased its operations within the country. The suit and two others were subsequently thrown out by California courts after it was concluded that “[c]ontrary to their sworn testimony, most of the plaintiffs never worked on Dole-affiliated banana farms and none were involved in the DBCP application process,” while similar lawsuits were filed in U.S. and Nicaraguan courts.[26]

In 2005, 23 people in Minnesota were sickened with E. coli O157:H7. The source of the bacteria was found to be Dole brand bagged lettuce.[21] Then in 2006, another E. coli outbreak that caused over 200 people to become ill and killed 3 more was linked to bagged spinach sold by Dole. The spinach was processed by Natural Selection Foods in California.[22]

Swedish director Fredrik Gertten made a documentary film about Dominguez and the alleged banana workers. The movie Bananas!* premiered in the 2009 Los Angeles Film Festival. Because Dole had serious concerns on what the film might reveal to the public, it urged festival officials to "immediately cease and desist" their sponsorship of the film.[27][28][29][30] The festival officials allowed the film to be screened, but it was not allowed to compete for placement in the competition. In addition, festival officials distributed information before the film's screening that indicated Dole believed the film to be factually inaccurate. Although the film was screened with a disclaimer from the festival, Gertten was subsequently sued for defamation by Dole.[31] The lawsuit was dropped on October 15, 2009, and in November 2010 a court in Los Angeles found in favour of the movie crew making it possible to release the movie in the USA, and ordering Dole to pay SEK 1.4 million (roughly USD 200,000) to the filmmakers.[32]
